MAX890L 智能低压 P-通道 MOSFET 电源开关说明书
General DescriptionThe MAX890L smart, low-voltage, P-channel, MOSF ET power switch is intended for high-side load-switching applications. This switch operates with inputs from +2.7V to +5.5V, making it ideal for both +3V and +5V systems. Internal current-limiting circuitry protects the input supply against overload. Thermal-overload pro-tection limits power dissipation and junction tempera-tures.The MAX890L’s maximum current limit is 1.2A. The cur-rent limit through the switch is programmed with a resistor from SET to ground. The quiescent supply cur-rent is a low 10µA. When the switch is off, the supply current decreases to 0.1µA.The MAX890L is available in an 8-pin SO package.ApplicationsPCMCIA Slots Access Bus Slots Portable EquipmentFeatures♦+2.7V to +5.5V Input Range ♦Programmable Current Limit ♦Low Quiescent Current10µA (typ) at V IN = +3.3V 0.1µA (typ) with Switch Off ♦Thermal Shutdown ♦FAULT Indicator Output ♦0.09Ω(typ) On-ResistanceMAX890L1.2A, Current-Limited, High-SideP-Channel Switch with Thermal Shutdown________________________________________________________________Maxim Integrated Products 1Pin ConfigurationTypical Operating Circuit 19-1146; Rev 4; 4/11*To order this unit in tape and reel, add (T) to the end of thepart number.**Dice are tested at T A = +25°C.+Denotes a lead(Pb)-free/RoHS-compliant package./V denotes an automotive qualified part.For pricing, delivery, and ordering information,please contact Maxim Direct at 1-888-629-4642,or visit Maxim’s website at .M A X 890L1.2A, Current-Limited, High-SideP-Channel Switch with Thermal Shutdown 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS(V IN = +3V,T A = 0°C to +85°C,unless otherwise noted.

Bypass IN with a 1μF capacitor to ground.IN 1, 2FUNCTIONNAME Detailed DescriptionThe MAX890L P-channel MOSF ET power switch limits output current to a programmed level. When the output current is increased beyond the programmed current limit, or 1.2A (I MAX ), the current also increases through the replica switch (I OUT /1110) and through R SET (F igure 1). The current-limit error amplifier compares the voltage across R SET to the internal +1.24V refer-ence and regulates the current back to the lesser of the programmed limit (I LIMIT ) or 1.2A.This switch is not bidirectional; therefore, the input volt-age must be higher than the output voltage.Setting the Current LimitThe MAX890L features internal current-limiting circuitry with a maximum programmable value (I MAX ) of 1.2A.F or best performance, set the current limit (I LIMIT )between 0.2 I MAX ≤I LIMIT ≤I MAX . This current limit remains in effect throughout the input supply-voltage range.Program the current limit with a resistor (R SET ) from SET to ground (Figure 2) as follows:I SET = I LIMIT / 1110R SET = 1.24V / I 8 = 1.38 x 103/ I LIMITwhere I LIMIT is the desired current limit.Short-Circuit ProtectionThe MAX890L is a short-circuit-protected switch. In the event of an output short circuit or current-overload con-dition, the current through the switch is limited by the internal current-limiting error amplifier to 1.5 x I LIMIT .When the fault condition is removed, the replica error amplifier sets the current limit back to I LIMIT .F or a high dV DS /dt during an output short-circuit condi-tion, the switch turns off and disconnects the input supply from the output. The current-limiting amplifier then slow-ly turns the switch on with the output current limited to 1.5 x I LIMIT . When the fault condition is removed, the current limit is set back to I LIMIT . Refer to the Output Short-Circuit Fast-Loop Response and Output Overload Slow-Loop Response in the Typical Operating Characteristics .Figure 1. Functional DiagramMAX890L1.2A, Current-Limited, High-SideP-Channel Switch with Thermal Shutdown_______________________________________________________________________________________7Thermal ShutdownThe MAX890L features thermal shutdown. The switch turns off when the junction temperature exceeds +135°C. Once the device cools by 10°C, the switch turns back on. If the fault short-circuit condition is not removed, the switch cycles on and off, resulting in a pulsed output.Fault IndicatorThe MAX890L provides a fault output (FAULT ). This open-drain output goes low when in current limit or when the die temperature exceeds +135°C. A 100k Ωpull-up resistor from FAULT to IN provides a logic-control signal.Applications InformationInput CapacitorTo limit the input voltage drop during momentary output short-circuit conditions, connect a capacitor from IN to GND. A 1µF ceramic capacitor is adequate for mostapplications; however, higher capacitor values further reduce the voltage drop at the input.Output CapacitorConnect a 0.1µF capacitor from OUT to GND. One function of this capacitor is to prevent inductive para-sitics from pulling OUT negative during turn-off.Layout and Thermal-DissipationConsiderationTo take full advantage of the switch-response time to output short-circuit conditions, it is very important to keep all traces as short as possible to reduce the effect of undesirable parasitic inductance. Place input and output capacitors as close as possible to the device (no more than 5mm).Under normal operating conditions, the package can dissipate and channel heat away. Calculate the maxi-mum power as follows:P = I 2LIMIT x R ON where R ON is the on-resistance of the switch.When the output is short circuited, the voltage drop across the switch equals the input supply. Hence, the power dissipated across the switch increases, as does the die temperature. If the fault condition is not removed, the thermal-overload-protection circuitry turns the switch off until the die temperature falls by 10°C. A ground plane in contact with the device helps dissipate additional heat.Package InformationF or the latest package outline information and land patterns (footprints), go to /packages . Note that a “+”, “#”, or “-” in the package code indicates RoHS status only.Package drawings may show a different suffix character, but the drawing pertains to the package regardless of RoHS status.Figure 2.

How to Use it:Instructions before operating(1). Once the unit is powered up, please check the 9V batterycontained in this unit, and if the battery voltage is insufficient, there will be asymbol “ ” being displayed on the screen, then the battery should bereplaced to ensure measurement accuracy.the jacks for test leads warns that for the prevention of internal circuit from being damaged, the input voltage or current should not exceed the rated value.(3). Before measuring, the range switch should be switched into the range needed.123456 (see Fig. 1)①② LCD③ Combination keys: MAX MIN/④ Range switch⑤ Jack for transistor testing ⑥ Input Jack1. DC Voltage Measurement(1). Insert the black test lead into “COM”, while insert the red test lead into “V”.the test leads in parallel with the power or load under test, the polarity shown by the unit is the polarity of the terminal connected by the red test lead.1) If the voltage being measured remains unknown, turn the range switch into the maximum range first and then gradually adjusting it downward.2) If “OL” is shown on the LCD, it indicates that it has exceeded the range, so the range should be switched into a higher one.higher than 1000V should be input into the unit, as though it is possible to display a higher voltage, but this may incur a risk of damaging internal wiring!4) In case the input impedance is around 10MΩ, it may result in measurement error if such load is connected into a circuit with high impedance. Under most circumstances, if the circuit impedance is less than 10kΩ, then the error is ignored (0.1% or even lower).5) Especially be cautious to avoid shock when measuring high voltage. 2. AC Voltage Measurement(1) Insert the black test lead into “COM”, while insert the red test lead into “V”.REV.1DATE:2015/07/07 (2) Switch the range switch into the range “ ”. Then connect thetest leads in parallel with the power or load under test.higher than 750V should be input into the unit, as though it is possibleto display a higher voltage, but this may incur a risk of damaginginternal wiring!1) If the current being measured remains unknown, turn the rangeswitch into the maximum range first and then gradually adjusting itdownward.2) If “OL” is shown on the LCD, it indicates that it has exceeded therange, so the range should be switched into a higher one.voltage higher than 600mA should be input into the unit, otherwiseindicates that no voltage higher than 20A should be input into theunit, otherwise F2 fuse may be blown.3. DC Current Measurement(1) Insert the black test lead into “COM” first, then when measuringcurrent equal or less than 600mA, insert the red test lead into “mAμA”,otherwise, insert the red test lead into the jack for 20A.test leads in series with the load under test, the polarity shown bythe unit is the polarity of the terminal connected by the red test lead.4. AC Current Measurement1) Insert the black test lead into “COM” first, then when measuringcurrent equal or less than 600mA, insert the red test lead into “mAμA”,otherwise, insert the red test lead into the jack for 20A.2) Switch the range switch into the range “ ”. Then connect thetest leads in series with the load under test.Refer to No. 1), 2) and 3) of the Notes for DC current measurement.5. Resistance(1) Input the black test lead into “COM”, while insert the red testlead into “Ω”.(2) Switch the range to range “Ω” and connect the test leads inparallel with the resistance under test.NotesNotesNotesNotesNotesNotes1) To ensure measurement accuracy, for the range of 600Ω：measured value=displayed value - value shown when test leads areshort connected.2) If the resistance under test is higher than the range selected, theunit will display “OL”. Then a higher range should be selected. Forany resistance higher than 1MΩ or even higher, it may take a fewseconds for the reading to become stable, which is normal whenmeasuring high resistance.3) The red test lead can also be used to check whether or not F1or F2 has been blown. If the “mAμA” jack is tested to be 1MΩ and“A” jack is tested to be 0Ω, then the fuse acts good. If the unit displays“OL”, then the fuse has been blown.4) In case of no input, i.e. the case of open-circuit, the unit displays“OL”.5) When checking the impedance of an internal circuit, the circuitunder test must be cut off from all power sources and all capacitivecharge must be discharged.6. Capacitance MeasurementThe unit may display a reading even if there is no input at all, whichis the distributed capacitance of the test leads. For the measurementof a resistance less than 1μF, this value has to be deducted from thefinal measured value to ensure measurement accuracy. Therefore,the relative measurement function of this unit can be used to haveit automatically deducted for the convenience of checking reading.1) The unit will display “OL” in case the capacitance to be measuredhas been short connected or exceeds the maximum range of theunit, the displayer will show “OL”.2) For the measurement of large capacitance, it is normal for theunit to take several seconds to stabilize its reading.3) To avoid unit damage or harm to the personal safety, the capacitorto be tested must have all its residual charge discharged before thetest, which is especially the case for capacitor with high voltage.7. Frequency Test1. Insert the red test lead into “Hz” jack, while insert the black testlead into “COM” jack.2. Switch the range switch into the range “Hz”. Then connect thetest leads in parallel with the frequency source, frequency valueThe input frequency must comply with the requirements stipulatedby the Technical Indexes.8. Test of DiodeInsert the black test lead into “COM” jack, while insert the red testlead into “V” jack (the polarity of red test lead is “+”). Switch the rangeswitch into the range “ ”. Then connect the test lead with thediode under test, the reading is the forward voltage drop of thediode. If the diode under test is in open circuit or its polarity is reverseconnected, the unit will display “OL”. For silicon p–n junction,approximately 500~800mV is generally considered normal.1) When measuring a connected diode, the circuit under test mustbe first cut off from all power sources and all capacitors must haveall their residual charge discharged.2) Only a diode with approximately 0~3V voltage can be measured.9. Buzzer Continuity TestInsert the black test lead into “COM”, while insert the red test leadinto “V”. Switch the range switch into the range “ ” and then connectthe test leads into the circuit under test. If both ends of the circuit hasa resistance higher than 100Ω，it is considered that the electric circuitis disconnected and the buzzer remains silence. If the resistancebetween both ends is found to be equal or less than 10Ω, it is thenconsidered that the electric circuit is well connected and the buzzerWhen measuring an energized circuit, the circuit under test mustfirst be cut off from all power sources and all capacitors must haveall their residual charge discharged.10. hFE Test for Transistors(1) Switch the range switch to the range “hFE”.(2) Once the transistor has been confirmed whether to be a NPNor PNP type, insert its base, emitter and collector separately intocorresponding jacks on the panel.(3) Approximate hFE value will be displayed on the displayer. Testcondition: 1b≈10μA, Vce≈1.2V。

③PTDX1 或 PTDX2 投入时，正序电压小于 30 伏，而任一相电流大于 0.02In，或负序电压大 于 8 伏时延时 10 秒报母线 PT 断线，只发出运行异常告警信号，不闭锁保护，待电压恢复正常 后装置也自动恢复正常。
不受起动继电器 QDJ 控制，JP1、JP2 均跳 1-2。 OUT 板：本装置的 JP1、JP2 均不需要跳线。 CPU 板：J4 跳上时，串口 1 为就地打印口，此时 JP4 一定要去除。J4 不跳时，串口 1 以 RS-485
方式输出，此时 JP4 为该串口的匹配电阻跳线。JP1 为时钟同步口的匹配电阻跳线，JP2 为串口 2 的 匹配电阻跳线，JP3 为串口 3 的匹配电阻跳线
低压解列的方式有两种，一种是低压故障解列，即三个线电压中任意一个小于低压定值， 均使得低压解列动作，为防止 PT 断线时误动作，可经电流闭锁（该功能可由控制字 IBSDY 投 退），即电压低于定值同时电流大于定值时，低压解列动作；一种是失压故障解列，即三个线 电压均小于定值时低压解列动作，也可经电流闭锁（该功能可由控制字 IBSDY 投退），即电压 低于定值同时电流小于定值时，失压解列动作。以上两种低压解列方式可由控制字 DYFS 选择， 即 DYFS 控制字为 1 时，为低压故障解列方式；DYFS 控制字为 0 时，为失压故障解列方式。
