KSP44为电话机中常用的高压三极管，当KSP44损坏而无法买到时，可用日光灯电路中常用的三极管 KSE13001进行彳弋换。KSE13001为FAlRCHl1.D公司产品，主要参数为BVCB。=400V,BVCE。 =400V,ICM=100mA,PCM=。.6W,hFE=40~80°KSE13001的封装形式虽然同样为T。-92,但其引脚电极的排序却与 KSP44不同，这一点在代换时要特殊留意。KSE13001引脚电极的识别方法是，当面对三极管的印字标识面时，其引脚电极1为基极B、2为集电极C、3为放射极E。
SS8550为目前市场上较为常见、易购的三极管，价格也比较便宜，单只售价仅0.3元左右。
KSP44为T。・92形式封装的NPN型三极管。其引脚电极的识别方法是，当面对三极管的印字标识面时，其引脚1为放射极E、2为基极B、3为集电极C。
KSP44的主要参数指标为：BVCB。=500V,BVCE。=400V,VCE(三)=。.5V,VBE(。N)=。 .75V,ICM=300mA,PCM=。.625W,TJ=150oC,hFE=40~2000
IRF740A为T。∙220形式封装的N沟道增加型MoS快速功率开关管。其引脚电极排序1为栅极G、2为漏极D、3为源极S。
IRF740A的主要参数指标为：VDSS=400V,ID=I。A,Ptot=120W,RDS(。N)S55。m。
当IRF740A损坏无法买到时，可用封装形式和引脚电极排序完全相同的N沟道增加型M。S开关管IRF740B、 IRF740或IRF730进行代换。IRF740、IRF740B的主要参数与IRF740A完全相同。IRF730的主要参数为 VDSS=400V,ID=5.5A,RDS(。N)31。其中IRF730的参数虽然与IRF740系列的相比略差，但对于150W以下功率的逆变器来说，其参数指标已经是绰绰有余了。

The inverting inputs of the LTC1165 allow P-channel switches to be replaced by lower resistance/cost N-channel switches while maintain-ing system drive polarity.The LTC1163/LTC1165 logic inputs are high impedance CMOS gates with ESD protection diodes to ground and therefore should not be forced below ground. The inputs can however, be driven above the power supply rail as there are no clamping diodes connected between the input pins and supply pin. This facilitates operation in mixed 5V/3V systems.Output PinsThe output pin is either driven to ground when the switch is turned OFF or driven above the supply rail when the switch is turned ON. The output is clamped to about 14V above ground by a built-in Zener clamp. This pin has a relatively high impedance when driven above the rail (the equivalent of a few hundred k Ω). Care should be taken to minimize any loading of this pin by parasitic resistance to ground or supply.Supply PinA 150Ω resistor should be inserted in series with the ground pin or supply pin if negative supply voltage tran-sients are anticipated. This will limit the current flowing from the power source into the LTC1163/LTC1165 to tens of milliamps during reverse battery conditions.OPERATIOUThe LTC1163/LTC1165 are triple micropower MOSFET drivers designed for operation over the 1.8V to 6V supply range and include the following functional blocks:3V Logic Compatible InputsThe LTC1163/LTC1165 inputs have been designed to accommodate a wide range of 3V and 5V logic families.The input threshold voltage is set at roughly 50% of the supply voltage and approximately 200mV of input hyster-esis is provided to ensure clean switching.The input enables all of the following circuit blocks: the bias generator, the high frequency oscillator and gate charge pump. Therefore, when the input is turned off, the entire circuit powers down and the supply current drops below 1µA.Standby Supply CurrentTEMPERATURE (°C)0S U P P L Y C U R R E N T (µA )5 4 3 2 1 0 –110203040LTC1163/65 • TPC07506070MOSFET Gate Drive CurrentGATE VOLTAGE ABOVE SUPPLY (V)1G A T E D R I V E C U R R E N T (µA )1010010004680.1210LTC1163/65 • TPC09Supply Current per Driver ONTEMPERATURE (°C)0S U P P L Y C U R R E N T (µA )300 250200150 100 50 010203040LTC1163/65 • TPC08506070/5LTC1163/LTC1165OPERATIOUGate Charge PumpGate drive for the power MOSFET is produced by an internal charge pump circuit which generates a gate volt-age substantially higher than the power supply voltage.The charge pump capacitors are included on chip and therefore no external components are required to generate gate drive.Controlled Gate Rise and Fall TimesWhen the input is switched ON and OFF, the gate is charged by the internal charge pump and discharged in a controlled manner. The charge and discharge rates have been set to minimize RFI and EMI emissions.BLOCK DIAGRA W(One Channel)APPLICATIO S I FOR ATIOW UU U Logic-Level MOSFET SwitchesThe LTC1163/LTC1165 are designed to operate with logic-level N-channel MOSFET switches. Although there is some variation among manufacturers, logic-level MOSFET switches are typically rated with V GS = 4V with a maximum continuous V GS rating of ±10V. R DS(ON) and maximum V DS ratings are similar to standard MOSFETs and there is generally little price differential. Logic-level MOSFETs are frequently designated by an “L” and are usually available in surface mount packaging. Some logic-level MOSFETs are rated with V GS up to ±15V and can be used in applications which require operation over the entire 1.8V to 6V range.Powering Large Capacitive LoadsElectrical subsystems in portable battery-powered equip-ment are typically bypassed with large filter capacitors to reduce supply transients and supply induced glitching. If not properly powered however, these capacitors may themselves become the source of supply glitching.For example, if a 100µF capacitor is powered through a switch with a slew rate of 0.1V/µs, the current during start-up is:I START = C(∆V/∆t)= (100 × 10–6)(1 × 105)= 10AObviously, this is too much current for the regulator (or output capacitor) to supply and the output will glitch by as much as a few volts.The startup current can be substantially reduced by limit-ing the slew rate at the gate of an N-channel as shown in Figure 1. The gate drive output of the LTC1163/LTC1165is passed through a simple RC network, R1 and C1, which substantially slows the slew rate of the MOSFET gate to approximately 1.5 × 10–4V/µs. Since the MOSFET is operating as a source follower, the slew rate at the source is essentially the same as that at the gate, reducing the startup current to approximately 15mA which is easilyGATEINPUT6LTC1163/LTC1165APPLICATIO S I FOR ATIOW UU U Figure 1. Powering a Large Capacitive Loadon a 3.3V supply which is compatible with 5V TTL and CMOS logic. (The LTC1163/LTC1165 cannot however, be driven by 3V logic when powered from a 5V supply because the threshold is approximately 2.5V.)TYPICAL APPLICATIO SUPCMCIA Card 3.3V/5V V CC SwitchNOTE: USE LTC1163 WITH NONINVERTING PCMCIA CONTROLLERSmanaged by the system regulator. R2 is required to eliminate the possibility of parasitic MOSFET oscillations during switch transitions. It is a good practice to isolate the gates of paralleled MOSFETs with 1k resistors to decrease the possibility of interaction between switches.Mixed 5V/3V SystemsBecause the input ESD protection diodes are referenced to ground instead of the supply pin, it is possible to drive the LTC1163/LTC1165 inputs from 5V CMOS or TTL logic even though the LTC1163/LTC1165 are powered from a 3.3V supply as shown in Figure 2. The input threshold voltage is approximately 50% of the supply voltage or 1.6VReverse Battery ProtectionThe LTC1163/LTC1165 can be protected against reverse battery conditions by connecting a 150Ω resistor in series with the ground pin or supply pin. The resistor limits the supply current to less than 24mA with –3.6V applied.Because the LTC1163/LTC1165 draw very little currentwhile in normal operation, the drop across the resistor is minimal. The 3.3V µP (or control logic) can be protected by adding 10k resistors in series with the input pins.Figure 2.

数字集成电路是将元器件和连线集成于同一半导体芯片上而制成的数字逻辑电路或系统。根据数字集成电路中包含的门电路或元、器件数量，可将数字集成电路分为小规模集成（SSI）电路、中规模集成MSI电路、大规模集成（LSI）电路、超大规模集成VLSI电路和特大规模集成（ULSI）电路。

·在条件允许的情况下，尽可能降低电源电压，如果电路工作频率比较低，用+5V电源供电最好；
·对使用的电源加限流措施，看
②电源电压的极性千万不能接反，电源正负极颠倒、接错，会因为过大电流而造成器件损坏。
③CM0S电路要求输人信号的幅度不能超过VDD～VSS，即满足VSS=V1=VDD。当 CM0S电路输入端施加的电压过高（大于电源电压）或过低（小于0V），或者电源电压突然变化时，电路电流可能会迅速增大，烧坏器件，这种现象称为可控硅效应。预防可控硅效应的措施主要有：
从功能上来看，数字集成电路内部可以分为数据通路（Data-path，也称为数据路径）和控制逻辑两大部分。这两大部分都是由大量的时序逻辑电路集成的，而且绝大部分都是同步的时序电路，因为时序电路被多个触发器或寄存器分成若干节点，而这些触发器在时钟的控制下会按同样的节拍来工作，可以简化设计。在长期的设计过程中，已经积累了很多标准的通用单元，比如选择器（也叫多路器，可以从多个输入数据中选一个输出）、比较器（用于比较两个数的大小）、加法器、乘法器、移位寄存器等等，这些单元电路形状规则，便于集成（这也是数字电路在集成电路中得到更好的发展的原因）。这些单元按设计要求连接在一起，形成数据通路，待处理的数据从输入端经过这条通路到输出端，便得到处理后的结果。同时，还需要由专门设计的控制逻辑，控制数据通路的各组成部件，按各自的功能要求和特定的时序关系和来配合工作。

LT3652_4.95-32V宽范围

13652faT YPICAL APPLICATIOND ESCRIPTION Charger for Solar PowerThe LT ®3652 is a complete monolithic step-down bat-tery charger that operates over a 4.95V to 32V inputvoltage range. The LT3652 provides a constant-current/constant-voltage charge characteristic, with maximum charge current externally programmable up to 2A. The charger employs a 3.3V ﬂ oat voltage feedback reference, so any desired battery ﬂ oat voltage up to 14.4V can be programmed with a resistor divider.The LT3652 employs an input voltage regulation loop, which reduces charge current if the input voltage falls below a programmed level, set with a resistor divider. When the LT3652 is powered by a solar panel, the input regulation loop is used to maintain the panel at peak output power.The LT3652 can be conﬁ gured to terminate charging when charge current falls below 1/10 of the programmed maximum (C/10). Once charging is terminated, the LT3652 enters a low-current (85μA) standby mode. An auto-re-charge feature starts a new charging cycle if the battery voltage falls 2.5% below the programmed ﬂ oat voltage. The LT3652 also contains a programmable safety timer, used to terminate charging after a desired time is reached.

V IN operating range is 4.95V to 32V. V IN must be 3.3V greater than the pro-grammed output battery ﬂ oat voltage (V BAT(FLT)) for reli-able start-up. (V IN – V BAT(FLT)) ≥ 0.75V is the minimum operating voltage, provided (V BOOST – V SW ) ≥ 2V. I VIN ~ 85μA after charge termination.V IN_REG (Pin 2): Input Voltage Regulation Reference. Maximum charge current is reduced when this pin is below 2.7V. Connecting a resistor divider from V IN to this pin enables programming of minimum operational V IN voltage. This is typically used to program the peak power voltage for a solar panel. The LT3652 servos the maximum charge current required to maintain the programmed operational V IN voltage, through maintaining the voltage on V IN_REG at or above 2.7V. If the voltage regulation feature is not used, connect the pin to V IN .SHDN (Pin 3): Precision Threshold Shutdown Pin. The enable threshold is 1.2V (rising), with 120mV of input hysteresis. When in shutdown mode, all charging functions are disabled. The precision threshold allows use of the SHDN pin to incorporate UVLO functions. If the SHDN pin is pulled below 0.4V, the IC enters a low current shutdown mode where V IN current is reduced to 15μA. Typical SHDN pin input bias current is 10nA. If the shutdown function is not desired, connect the pin to V IN .CHRG (Pin 4): Open-Collector Charger Status Output; typically pulled up through a resistor to a reference volt-age. This status pin can be pulled up to voltages as high as V IN when disabled, and can sink currents up to 10mA when enabled. During a battery charging cycle, if required charge current is greater than 1/10 of the programmed maximum current (C/10), CHRG is pulled low. A tem-perature fault also causes this pin to be pulled low. After C/10 charge termination or, if the internal timer is used for termination and charge current is less than C/10, the CHRG pin remains high-impedance.FAULT (Pin 5): Open-Collector Charger Status Output; typically pulled up through a resistor to a reference volt-age. This status pin can be pulled up to voltages as high as V IN when disabled, and can sink currents up to 10mA when enabled. This pin indicates fault conditions during a battery charging cycle. A temperature fault causes this pinto be pulled low. If the internal timer is used for termina-tion, a bad battery fault also causes this pin to be pulled low. If no fault conditions exist, the FAULT pin remains high-impedance.TIMER (Pin 6): End-Of-Cycle Timer Programming Pin. If a timer-based charge termination is desired, connect a capacitor from this pin to ground. Full charge end-of-cycle time (in hours) is programmed with this capacitor following the equation: t EOC = C TIMER • 4.4 • 106A bad battery fault is generated if the battery does not achieve the precondition threshold voltage within one-eighth of t EOC , or: t PRE = C TIMER • 5.5 • 105A 0.68μF capacitor is typically used, which generates a timer EOC at three hours, and a precondition limit time of 22.5 minutes. If a timer-based termination is not desired, the timer function is disabled by connecting the TIMER pin to ground. With the timer function disabled, charging terminates when the charge current drops below a C/10 threshold, or I CHG(MAX)/10V FB (Pin 7): Battery F loat Voltage F eedback Reference. The charge function operates to achieve a ﬁ nal ﬂ oat voltage of 3.3V on this pin. Output battery ﬂ oat voltage (V BAT(FLT)) is programmed using a resistor divider. V BAT(FLT) can be programmed up to 14.4V.The auto-restart feature initiates a new charging cyclewhen the voltage at the V FB pin falls 2.5% below the ﬂoat voltage reference.The V FB pin input bias current is 110nA. Using a resistor divider with an equivalent input resistance at the V FB pin of 250k compensates for input bias current error.Required resistor values to program desired V BAT(FLT) follow the equations:R1 = (V BAT(FLT) • 2.5 • 105)/3.3 (Ω) R2 = (R1 • 2.5 • 105)/(R1 - (2.5 • 105))(Ω)R1 is connected from BAT to V FB , and R2 is connected from V FB to ground.LT365273652faNTC (Pin 8): Battery Temperature Monitor Pin. This pin is the input to the NTC (Negative Temperature Coefﬁ cient) thermistor temperature monitoring circuit. This function is enabled by connecting a 10kΩ, B = 3380 NTC thermistor from the NTC pin to ground. The pin sources 50μA, and monitors the voltage across the 10kΩ thermistor. When the voltage on this pin is above 1.36 (T < 0°C) or below 0.29V (T > 40°C), charging is disabled and the CHRG and FAULT pins are both pulled low. If internal timer termina-tion is being used, the timer is paused, suspending the charging cycle. Charging resumes when the voltage on NTC returns to within the 0.29V to 1.36V active region. There is approximately 5°C of temperature hysteresis associated with each of the temperature thresholds. The temperature monitoring function remains enabled while the thermistor resistance to ground is less than 250k, so if this function is not desired, leave the NTC pin unconnected.BAT (Pin 9): Charger Output Monitor Pin. Connect a 10μF decoupling capacitance (C BAT ) to ground. Depend-ing on application requirements, larger value decoupling capacitors may be required. The charge function operates to achieve the programmed output battery ﬂ oat voltage (V BAT(FLT)) at this pin. This pin is also the reference for the current sense voltage. Once a charge cycle is termi-nated, the input bias current of the BAT pin is reduced to < 0.1μA, to minimize battery discharge while the charger remains connected.SENSE (Pin 10): Charge Current Sense Pin. Connect the inductor sense resistor (R SENSE ) from the SENSE pin to the BAT pin. The voltage across this resistor sets the averagecharge current. The maximum charge current (I CHG(MAX)) corresponds to 100mV across the sense resistor. This resistor can be set to program maximum charge cur-rent as high as 2A. The sense resistor value follows the relation:R SENSE = 0.1/I CHG(MAX) (Ω)Once a charge cycle is terminated, the input bias current of the SENSE pin is reduced to < 0.1μA, to minimize battery discharge while the charger remains connected.BOOST (Pin 11): Bootstrapped Supply Rail for Switch Drive. This pin facilitates saturation of the switch transistor. Connect a 1μF or greater capacitor from the BOOST pin to the SW pin. Operating range of this pin is 0V to 8.5V, referenced to the SW pin. The voltage on the decoupling capacitor is refreshed through a rectifying diode, with the anode connected to either the battery output voltage or an external source, and the cathode connected to the BOOST pin.SW (Pin 12): Switch Output Pin. This pin is the output of the charger switch, and corresponds to the emitter of the switch transistor. When enabled, the switch shorts the SW pin to the V IN supply. The drive circuitry for this switch is bootstrapped above the V IN supply using the BOOST supply pin, allowing saturation of the switch for maximum efﬁ ciency. The effective on-resistance of the boosted switch is 0.175Ω.SGND (Pin 13): Ground Reference and Backside Exposed Lead Frame Thermal Connection. Solder the exposed lead frame to the PCB ground plane.P IN FUNCTIONSLT365283652faB LOCK DIAGRAM+–LT365293652faA PPLICATIONS INFORMATION OverviewL T3652 is a complete monolithic, mid-power , multi-chem-istry buck battery charger , addressing high input voltageapplications with solutions that require a minimum of exter-nal components. The IC uses a 1MHz constant frequency,average-current mode step-down architecture.The L T3652 incorporates a 2A switch that is driven by a bootstrapped supply to maximize efficiency during charging cycles. Wide input range allows operation to fullcharge from voltages as high as 32V . A precision thresholdshutdown pin allows incorporation of UVLO functionalityusing a simple resistor divider . The IC can also be put intoa low-current shutdown mode, in which the input supplybias is reduced to only 15μA.The L T3652 employs an input voltage regulation loop, which reduces charge current if a monitored input volt-age falls below a programmed level. When the L T3652 ispowered by a solar panel, the input regulation loop is usedto maintain the panel at peak output power .The L T3652 automatically enters a battery precondition mode if the sensed battery voltage is very low. In this mode,the charge current is reduced to 15% of the programmed maximum, as set by the inductor sense resistor , R SENSE . Once the battery voltage reaches 70% of the fully charged float voltage, the IC automatically increases maximum charge current to the full programmed value.The L T3652 can use a charge-current based C/10 termina-tion scheme, which ends a charge cycle when the battery charge current falls to one tenth of the programmed maximum charge current. The L T3652 also contains an internal charge cycle control timer , for timer-based termina-tion. When using the internal timer , the IC combines C/10 detection with a programmable time constraint, during which the charging cycle can continue beyond the C/10 level to top-off a battery. The charge cycle terminates when a specific time elapses, typically 3 hours. When the timer-based scheme is used, the IC also supports bad battery detection, which triggers a system fault if a battery stays in precondition mode for more than one eighth of the total charge cycle time.Once charging is terminated, the L T3652 automaticallyenters a low-current standby mode where supply biascurrents are reduced to 85μA. The IC continues to monitorthe battery voltage while in standby, and if that voltagefalls 2.5% from the full-charge float voltage, the L T3652engages an automatic charge cycle restart. The IC alsoautomatically restarts a new charge cycle after a bad bat-tery fault once the failed battery is removed and replaced with another battery.The L T3652 contains provisions for a battery temperaturemonitoring circuit. This feature monitors battery tempera-ture using a thermistor during the charging cycle. If thebattery temperature moves outside a safe charging rangeof 0°C to 40°C, the IC suspends charging and signals afault condition until the temperature returns to the safecharging range.The L T3652 contains two digital open-collector outputs,which provide charger status and signal fault conditions.These binary-coded pins signal battery charging, standbyor shutdown modes, battery temperature faults, and badbattery faults.General Operation (See Block Diagram)The L T3652 uses average current mode control loop architecture, such that the IC servos directly to average charge current. The L T3652 senses charger output voltage through a resistor divider via the V FB pin. The difference between the voltage on this pin and an internal 3.3V volt-age reference is integrated by the voltage error amplifier (V-EA). This amplifier generates an error voltage on its output (I TH ), which corresponds to the average current sensed across the inductor current sense resistor , R SENSE , which is connected between the SENSE and BAT pins. The I TH voltage is then divided down by a factor of 10, and imposed on the input of the current error amplifier (C-EA). The difference between this imposed voltage and the current sense resistor voltage is integrated, with the resulting voltage (V C ) used as a threshold that is compared against an internally generated ramp. The output of this comparison controls the charger’s switch.LT3652103652faA PPLICATIONS INFORMATION The I TH error voltage corresponds linearly to average current sensed across the inductor current sense resistor , allowing maximum charge current control by limiting the effective voltage range of I TH . A clamp limits this voltage to 1V which, in turn, limits the current sense voltage to 100mV . This sets the maximum charge current, or the current delivered while the charger is operating in con-stant-current (CC) mode, which corresponds to 100mV across R SENSE . The I TH voltage is pulled down to reduce this maximum charge current should the voltage on the V IN_REG pin falls below 2.7V (V IN_REG(TH)) or the die tem-perature approaches 125°C.If the voltage on the V FB pin is below 2.3V (V FB(PRE)), the LT3652 engages precondition mode. During the precondition interval, the charger continues to operate in constant-current mode, but the maximum charge current is reduced to 15% of the maximum programmed value as set by R SENSE .When the charger output voltage approaches the float volt-age, or the voltage on the V FB pin approaches 3.3V (V FB(FL T)), the charger transitions into constant-voltage (CV) mode and charge current is reduced from the maximum value. As this occurs, the I TH voltage falls from the limit clamp and servos to lower voltages. The IC monitors the I TH volt-age as it is reduced, and detection of C/10 charge current is achieved when I TH = 0.1V . If the charger is configured for C/10 termination, this threshold is used to terminate the charge cycle. Once the charge cycle is terminated, the CHRG status pin becomes high-impedance and the charger enters low-current standby mode.The L T3652 contains an internal charge cycle timer that terminates a successful charge cycle after a programmed amount of time. This timer is typically programmed to achieve end-of-cycle (EOC) in 3 hours, but can be con-figured for any amount of time by setting an appropriate timing capacitor value (C TIMER ). When timer termination is used, the charge cycle does not terminate when C/10 is achieved. Because the CHRG status pin responds tothe C/10 current level, the IC will indicate a fully-charged battery status, but the charger continues to source low currents into the battery until the programmed EOC time has elapsed, at which time the charge cycle will terminate. At EOC when the charging cycle terminates, if the battery did not achieve at least 97.5% of the full float voltage, charging is deemed unsuccessful, the L T3652 re-initiates, and charging continues for another full timer e of the timer function also enables bad-battery detec-tion. This fault condition is achieved if the battery does not respond to preconditioning, such that the charger remains in (or enters) precondition mode after 1/8th of the programmed charge cycle time. A bad battery fault halts the charging cycle, the CHRG status pin goes high-impedance, and the FAUL T pin is pulled low.When the L T3652 terminates a charging cycle, whether through C/10 detection or by reaching timer EOC, the average current mode analog loop remains active, but the internal float voltage reference is reduced by 2.5%. Because the voltage on a successfully charged battery is at the full float voltage, the voltage error amp detects an over-voltage condition and I TH is pulled low. When the voltage error amp output drops below 0.3V , the IC enters standby mode, where most of the internal circuitry is dis-abled, and the V IN bias current is reduced to 85μA. When the voltage on the V FB pin drops below the reduced float reference level, the output of the voltage error amp will climb, at which point the IC comes out of standby mode and a new charging cycle is initiated.V IN Input SupplyThe L T3652 is biased directly from the charger input supply through the V IN pin. This supply provides large switched currents, so a high-quality, low ESR decoupling capacitor is recommended to minimize voltage glitches on V IN . The V IN decoupling capacitor (C VIN ) absorbs all input switchingripple current in the charger , so it must have an adequate ripple current rating. RMS ripple current (I CVIN(RMS)) is: I CVIN(RMS) ≅ I CHG(MAX) • (V BAT / V IN )•([V IN / V BAT ] – 1)1/2,where I CHG(MAX) is the maximum average charge current (100mV/R SENSE ). The above relation has a maximum at V IN = 2 • V BAT , where: I CVIN(RMS) = I CHG(MAX)/2.The simple worst-case of ½ • I CHG(MAX) is commonly used for design.Bulk capacitance is a function of desired input ripple volt-age (ΔV IN ), and follows the relation:C IN(BULK) = I CHG(MAX) • (V BAT /V IN ) / ΔV IN (μF)Input ripple voltages above 0.1V are not recommended. 10μF is typically adequate for most charger applica-tions.Charge Current ProgrammingThe L T3652 charger is configurable to charge at average currents as high as 2A. Maximum charge current is set by choosing an inductor sense resistor (R SENSE ) such that the desired maximum average current through that sense resistor creates a 100mV drop, or: R SENSE = 0.1 / I CHG(MAX)where I CHG(MAX) is the maximum average charge current. A 2A charger , for example, would use a 0.05Ω sense resistor .BOOST SupplyThe BOOST bootstrapped supply rail drives the internal switch and facilitates saturation of the switch transistor . Operating range of the BOOST pin is 0V to 8.5V , as refer-A PPLICATIONS INFORMATION Figure 1. Programming Maximum Charge Current Using R SENSESENSEenced to the SW pin. Connect a 1μF or greater capacitor from the BOOST pin to the SW pin.The voltage on the decoupling capacitor is refreshed through a diode, with the anode connected to either the battery output voltage or an external source, and the cathode connected to the BOOST pin.

Altronic EPC-200C 引擎性能控制器说明书

Altronic, LLC – A Member of the HOERBIGER GroupEPC SERIESEngine Performance Controllern Improve engine performance and efficiencyn Electronic control of ignition timing and air/fuel ratio n User-configurable for any enginen Fail-safe design features and fault annunciation n Seven discrete outputs for sequence controln 8-digit LCD display of status and operating parameters n RS422 communications interfacen CSA-Certified for Class I, Division 2, Group DHazardous AreasThe Altronic EPC-200C Engine Performance Controller is de-signed to maximize engine performance and efficiency. Micro-processor-based, the EPC electronically controls ignition timing and air/fuel ratio replacing the traditional pneumatic control system for these functions. Engine RPM plus up to four other analog inputs can be used as control variables; typically, these would include fuel manifold pressure, air manifold pressure and air manifold temperature. The four inputs and two analog outputs are in the form of 1–5 volt or 4–20 ma signals for easy interfacing with available transducers. The EPC is specially designed to operate in conjunction with Altronic II-CPU and Altronic III-CPU.In addition to the two analog control functions (ignition timing and air/fuel ratio), the EPC-200C also has six user-programma-ble solid-state relay outputs related to the common start-up se-quencing functions such as purge, overcrank, crank disconnect, flooding, etc. A seventh discrete output provides a signal in the event of overspeed, overload or loss of any input; if this occurs, timing and air/fuel ratio are set to preset values. In addition, there is a manual override mode to allow changing and checking of program data while the engine is running.The EPC-200C has a RS422 interface for communications capability with other process or control computers.CERTIFIEDCLASS I, DIVISION 2,GROUP DTypical ApplicationExample: Turbocharged Gas Engine with Wastegate Controllerfor Air Manifold PressureThe chart indicates the most common input variables used. The fifth input channel gives additional flexibility and capability for more sophisticated control programs.For Ignition Timing control, the user chooses one input (for exam-ple, RPM) as the primary control factor. Other factors are used to appropriately modify the timing curves for load and temperature. For Air/Fuel Ratio control, fuel pressure is the primary control factor with air manifold temperature as a modifier. Other control strategies are possible, for example, based on different inputs such as fuel BTU value or exhaust oxygen content.EPC-200 FeaturesGeneral Operation — The EPC-200C performs the functions of a typical pneumatic control system for a gas engine with exhaust-driven turbocharger. The outputs are controlled by RPM and up to four other variables. Response to the inputs is controlled by entries through the the EPC’s dealed membrane keyboard, giving the user total access to the operating parameters.Keyboard Entry by User — Operating curves are entered inj (x,y) coordinate format: other data is entered and displayed in com-mon engineering units (RPM, psi, degrees F., etc.). No algebra or computer programming knowledge is required. Access to critical control variables is password-protected so that accidental contact with the keyboard has no effect.Diagnostic Capability — Diagnostic messages warn of various ab-normal conditions while the engine is in operation or the first-out fault cause for the error output which can be used to alarmk or shut down the engine. Loss of any specific input or out-of-range conditions are examples of the factors which are specifically an-nunciated.Rs422 Communications Capability — Communications capability is provided for interfacing to process control computers. The data on any channel can be read, including the ignition timing and wa-stegate position values. All setpoints can be read and/or altered remotely. RS422 signals have the capability for long distance transmission. In addition, software for direct, readable display and control from a remote IBM-compatible PC will be available.4-20mA Outputs — The two major contol outputs, Ignition Timing Retard and Wastegate Position, are output as 4-20mA (1-5 V.) signals. Additionally, the user has control over the Proportional Band and Reset Time Response values. These determine how the EPC responds to changes in input data; an important feature for any control device interfacing with a large, mechanical machine. The EPC-200C performs the functions of a typical pneumatic control system for a gas engine with exhaust-driven turbocharger. The outputs are controlled by RPM and up to four other variables. Response to the inputs is controlled by entries through the the EPC’s dealed membrane keyboard, giving the user total access to the operating parameters.Display Capabilityn Display value of all analog input signalsn Display the output value for ignition timing, air manifold pressure and waste gate positionn Display all (x,y) coordinate valuesn Display PI response valuesn Diagnostic channels for error messages when operating or first-out fault Data Entered by User1.
