DS1603;中文规格书,Datasheet资料

Multiple revisions of any device may be simultaneously available through various sales channels. For information about device errata, click here: /errata .FEATURES§ Two 32-bit counters keep track of real -time and elapsed time§ Counters keep track of seconds for over 125 years§ Battery powered counter counts seconds from the time battery is attached until V BAT is less than 2.5V§ V CC powered counter counts seconds while V CC is above V TP and retains the count in the absence of V CC under battery backup power § Clear function resets selected counter to 0 § Read/write serial port affords low pin count § Powered internally by a lithium energy cell that provides over 10 years of operation§ One-byte protocol defines read/write, counter address and software clear function§ Self-contained crystal provides an accuracy of ±2 min per month§ Operating temperature range of 0°C to +70°C § Low-profile SIP module§ Underwriters Laboratory (UL) recognized PIN ASSIGNMENTPIN DESCRIPTIONRST- Reset CLK - ClockDQ - Data Input/Output GND - Ground V CC - +5VOSC - 1Hz Oscillator Output NC- No ConnectDESCRIPTIONThe DS1603 is a real -time clock/elapsed time counter designed to count seconds when V CC power is applied and continually count seconds under battery backup power with an additional counter regardless of the condition of V CC . The continuous counter can be used to derive time of day, week, month, and year by using a software algorithm. The V CC powered counter will automatically record the amount of time that V CC power is applied. This function is particularly useful in determining the operational time of equipment in which the DS1603 is used. Alternatively, this counter can also be used under software control to record real -time events. Communication to and from the DS1603 takes place via a 3-wire serial port. A 1-byte protocol selects read/ write functions, counter clear functions and oscillator trim. The device contains a 32.768kHz crystal that will keep track of time to within ±2 min/mo. An internal lithium energy source contains enough energy to power the continuous seconds counter for over 10 years.OPERATIONThe main elements of the DS1603 are shown in Figure 1. As shown, communications to and from the elapsed time counter occur over a 3-wire serial port. The port is activated by driving RST to a high state.V CC RST DQ NC CLK OSC GND DS1603Elapsed Time Counter Moduleselect, register clear, and oscillator trim information. Each bit is serially input on the rising edge of the clock input. After the first eight clock cycles have loaded the protocol register with a valid protocol additional clocks will output data for a read or input data for a w rite. V CC must be present to access the DS1603. If V CC < V TP, the DS1603 will switch to internal power and disable the serial port to conserve energy. When running off of the internal power supply, only the continuous counter will continue to count and the counter powered by V CC will stop, but retain the count, which had accumulated when V CC power was lost. The 32-bit V CC counter is gated by V CC and the internal 1Hz signal.PROTOCOL REGISTERThe protocol bit definition is shown in Figure 2. Valid protocols and the resulting actions are shown in Table 1. Each data transfer to the protocol register designates what action is to occur. As defined, the MSB (bit 7 which is designated ACC) selects the 32-bit continuous counter for access. If ACC is a logical 1 the continuous counter is selected and the 32 clock cycles that follow the protocol will either read or write this counter. If the counter is being read, the contents will be latched into a different register at the end of protocol and the latched contents will be read out on the next 32 clock cycles. This avoids reading garbled data if the counter is clocked by the oscillator during a read. Similarly, if the counter is to be written, the data is buffered in a register and all 32 bits are jammed into the counter simultaneously on the rising edge of the 32nd clock. The next bit (bit 6 which is designated AVC) selects the 32–bit V CC active counter for access. If AVC is a logical 1 this counter is selected and the 32 clock cycles that follow will either read or write this counter. If both bit 7 and bit 6 are written to a logic high, all clock cycles beyond the protocol are ignored and bit 5, 4, and 3 are loaded into the oscillator trim register. A value of binary 3 (011) will give a clock accuracy of ±120 seconds per month at +25°C. Increasing the binary number towards 7 will cause the real-time clock to run faster. Conversely, lowering the binary number towards 0 will cause the clock to run slower. Binary 000 will stop the oscillator completely. This feature can be used to conserve battery life during storage. In this mode the internal power supply current is reduced to 100 nA maximum. In applications where oscillator trimming is not practical or not needed, a default setting of 011 is recommended. Bit 2 of protocol (designated CCC) is used to clear the continuous counter. When set to logic 1, the continuous counter will reset to 0 when RST is taken low. Bit 1 of protocol (designated CVC) is used to clear the V CC active counter. When set to logical 1, the V CC active counter will reset to 0 when RST is taken low. Both counters can be reset simultaneously by setting CCC and CVC both to a logical 1. Bit 0 of the protocol (designated RD) determines whether the 32 clocks to follow w ill write a counter or read a counter. When RD is set to a logical 0 a write action will follow when RD is set to a logical 1 a read action will follow. When sending the protocol, 8 bits should always be sent. Sending less than 8 bits can produce erroneous results. If clearing the counters or trimming the oscillator, the data transfer can be terminated after the 8-bit protocol is sent. However, when reading or writing the counters, 32 clock cycles should always follow the protocol.RESET AND CLOCK CONTROLAll data transfers are initiated by driving the RST input high. The RST input has two functions. First, RST turns on the serial port logic, which allows access to the protocol register for the protocol data entry. Second, the RST signal provides a method of terminating the protocol transfer or the 32-bit counter transfer. A clock cycle is a sequence of a rising edge followed by a falling edge. For write inputs, data must be valid during the rising edge of the clock. Data bits are output on the falling edge of the clock when data is being read. All data transfers terminate if the RST input is transitioned low and the DQ pin goes to a high-impedance state. RST should only be transitioned low while the clock is high to avoid disturbing the last bit of data. All data transfers must consist of 8 bits when transferring protocol only or 8 + 32 bits when reading or writing either counter. Data tran sfer is illustrated in Figure 3.DATA INPUTFollowing the 8-bit protocol that inputs write mode, 32 bits of data are written to the selected counter on the rising edge of the next 32 CLK cycles. After 32 bits have been entered any additional CLK cycles will be ignored until RST is transitioned low to end data transfer and then high again to begin new data transfer.DATA OUTPUTFollowing the eight CLK cycles that input read mode protocol, 32 bits of data will be output from the selected counter on the next 32 CLK cycles. The first data bit to be transmitted from the selected 32-bit counter occurs on the falling edge after the last bit of protocol is written. When transmitting data from the selected 32-bit counter, RST must remain at high level as a transition to low level will terminate data transfer. Data is driven out the DQ pin as long as CLK is low. When CLK is high the DQ pin is tristated. OSCILLATOR OUTPUTPin 6 of the DS1603 module is a 1Hz output signal. This signal is present only when V CC is applied and greater than the internal power supply. However, the output is guaranteed to meet TTL requirement only while V CC is within normal limits. This output can be used as a 1-second interrupt or time tick needed in some applications.INTERNAL POWERThe internal battery of the DS1603 module provides 35mAh and will run the elapsed time counter for over 10 years in the absence of power.PIN DESCRIPTIONSV CC, GND – DC power is provided to the device on these pins. V CC is the +5V input. When 5V is applied within normal limits, the device is fully accessible and data can be written and read. When a 3V battery is connected to the device and V CC is below 1.25 x V BAT, reads and writes are inhibited. As V CC falls below V BAT the continuous counter is switched over to the internal battery.CLK (Serial Clock Input) – CLK is used to synchronize data movement on the serial interface.DQ (Data Input/Output) – The DQ pin is the bi-directional data pin for the 3-wire interface.RST (Reset) – The reset signal must be asserted high during a read or a write.OSC (One Hertz Output Signal) – This signal is only present when Vcc is at a valid level and the oscillator is enabled.Figure 1.

When circuit boards are inserted into a live backplane, the bypass capacitors at the input of the board’s power module or switching power supply can draw large inrush currents as they charge. Uncontrolled inrush currents can cause glitches on the system power supply and damage components on the board.circuit cards preventing damage to connectors, board components, and prevent glitches on the power-supply rail. Both the MAX5921/MAX5939 provide undervolt-age, overvoltage, and overcurrent protection. The MAX5921/MAX5939 ensure that the input voltage is sta-ble and within tolerance before applying power to the load. The device also provides protection against input voltage steps by limiting the load current to a safe level without turning off power to the load.MAX5921/MAX5939-48V Hot-Swap Controllers with External R SENSE and High Gate Pulldown Current_______________________________________________________________________________________9Board InsertionFigure 6a shows a typical hot-swap circuit for -48V sys-tems. When the circuit board first makes contact with the backplane, the DRAIN to GATE capacitance (C gd )of Q1 pulls up the GATE voltage to roughly IV EE x (C gd /C gd + C gs )I. The MAX5921/MAX5939 feature an internal dynamic clamp between GATE and V EE to keep the gate-to-source voltage of Q1 low during hot insertion preventing Q1 from passing an uncontrolled current to the load. F or most applications, the internal clamp between GATE and V EE of the MAX5921/MAX5939 eliminates the need for an external gate-to-source capacitor. The resistor R3 limits the current into the clamp circuitry during card insertion.Power-Supply RampingThe MAX5921/MAX5939 can reside either on the back-plane or the removable circuit board (Figure 6a). Power is delivered to the load by placing an external N-chan-nel MOSFET pass transistor in the power-supply path.After the circuit board is inserted into the backplane,and the supply voltage at V EE is stable and within the undervoltage and overvoltage tolerance, the MAX5921/MAX5939 gradually turn on the external MOSFET by charging the gate of Q1 with a 45µA cur-rent source. Capacitor C2 provides a feedback signal to accurately limit the inrush current.The inrush current can be calculated:I INRUSH = I PU x C L / C2where C L is the total load capacitance, C3 + C4, and I PU is the gate pullup current.Figure 6b shows the inrush current waveform. The cur-rent through C2 controls the GATE voltage. At the end of the DRAIN ramp, the GATE voltage is charged to its final value. The GATE-to-SENSE clamp limits the maxi-mum ∆V GATE to 18V.Board RemovalIf the circuit card is removed from the backplane, the volt-age at the UV falls below the UVLO detect threshold, and the MAX5921/MAX5939 turn off the external MOSFET.Current Limit and Electronic CircuitBreakerThe MAX5921/MAX5939 provide current-limiting and cir-cuit-breaker features that protect against excessive load current and short-circuit conditions. The load current is monitored by sensing the voltage across an external sense resistor connected between V EE and SENSE.Figure 6a. Inrush Control Circuitry/Typical Application CircuitM A X 5921/M A X 5939-48V Hot-Swap Controllers with External R SENSE and High Gate Pulldown Current 10______________________________________________________________________________________If the voltage between V EE and SENSE reaches the cur-rent-limit trip voltage (V CL ), the MAX5921/MAX5939 pull down the GATE and regulate the current through the external MOSF ET such that V SENSE - V EE <V CL . If the current drawn by the load drops below V CL / R SENSE limit, the GATE voltage rises again. However, if the load current is at the regulation limit of V CL / R SENSE for a peri-od of t PHLCL , the electronic circuit breaker trips, causing the MAX5921/MAX5939 to turn off the external MOSFET.After an overcurrent fault condition, the MAX5921 auto-matically restarts after t OFF has elapsed. The MAX5939circuit breaker is reset by toggling UV or by cycling power. Unless power is cycled to the MAX5939, the device waits until t OFF has elapsed before turning on the gate of the external FET.Load-Current RegulationThe MAX5921/MAX5939 accomplish load-current regu-lation by pulling current from GATE whenever V SENSE -V EE > V CL . This decreases the gate-to-source voltage of the external MOSFET, thereby reducing the load current.When V SENSE - V EE < V CL , the MAX5921/MAX5939 pulls GATE high by a 45µA (I PU ) current.Exponential Current RegulationThe MAX5921/MAX5939 provide an exponential pull-down current to turn off the external FET in response to overcurrent conditions. The GATE pulldown current increases (see Typical Operating Characteristics ) in response to V SENSE - V EE potentials greater than 50mV (V CL ).Load Current Regulation (Short-Circuit Condition)The MAX5921/MAX5939 devices also include a very fast high-current pulldown source connected to GATE (see Typical Operating Characteristics ). The high-cur-rent pulldown activates if V SENSE exceeds V EE by 650mV (typ) during a catastrophic overcurrent or short-circuit fault condition. The high-current pulldown circuit sinks as much as 450mA from GATE to turn off the external MOSFET.Immunity to Input Voltage StepsThe MAX5921/MAX5939 guard against input voltage steps on the input supply. A rapid increase in the input supply voltage (V DD - V EE increasing) causes a current step equal to I = C L x ∆V IN / ∆t, proportional to the input voltage slew rate (∆V IN / ∆t). If the load current exceeds V CL / R SENSE during an input voltage step, the MAX5921/MAX5939 current limit activates, pulling down the gate voltage and limiting the load current to V CL / R SENSE . The DRAIN voltage (V DRAIN ) then slews at a slower rate than the input voltage. As the drain voltage starts to slew down, the drain-to-gate feedback capacitor C2 pushes back on the gate, reducing the gate-to-source voltage (V GS ) and the current through the external MOSF ET.Once the input supply reaches its final value, the DRAIN slew rate (and therefore the inrush current) is limited by the capacitor C2 just as it is limited in the startup condi-tion (see the Power-Supply Ramping section). To ensure correct operation, R SENSE must be chosen to provide a current limit larger than the sum of the load current and the dynamic current into the load capacitance in the slewing mode.If the load current plus the capacitive charging current is below the current limit, the circuit breaker does not trip.Undervoltage and Overvoltage ProtectionUse UV and OV to detect undervoltage and overvoltage conditions. UV and OV internally connect to analog com-parators with 130mV (UV) and 50mV (OV) of hysteresis.When the UV voltage falls below its threshold or the OV voltage rises above its threshold, GATE pulls low. GATE is held low until UV goes high and OV is low, indicating that the input supply voltage is within specification.

External component selection is driven by the load requirement and begins with the selection of L fol-lowed by C IN and C OUT .Inductor SelectionFor most applications, the value of the inductor will fall in the range of 1µH to 4.7µH. Its value is chosen based on the desired ripple current. Large value inductors lower ripple current and small value inductors result in higher ripple currents. Higher V IN or V OUT also increases the ripple current as shown in equation 1. A reasonable starting point for setting ripple current is ∆I L = 240mA (40% of 600mA).∆=()()−⎛⎝⎜⎞⎠⎟I f L V V V L OUT OUT IN 11(1)The DC current rating of the inductor should be at least equal to the maximum load current plus half the ripple current to prevent core saturation. Thus, a 720mA rated inductor should be enough for most applications (600mA + 120mA). For better efficiency, choose a low DC-resis-tance inductor.Inductor Core SelectionDifferent core materials and shapes will change the size/current and price/current relationship of an inductor.Toroid or shielded pot cores in ferrite or permalloy mate-rials are small and don’t radiate much energy, but gener-ally cost more than powdered iron core inductors with similar electrical characteristics. The choice of which style inductor to use often depends more on the price vs size requirements and any radiated field/E MI requirements than on what the LTC3406-1.2 requires to operate. Table 1 shows some typical surface mount inductors that work well in LTC3406-1.2 applications.Table 1.

To prevent large voltage transients, a low ESR input capacitor sized for the maximum RMS current must be used. The maximum RMS capacitor current is given by:C requiredI I V V V V IN RMS OMAXOUT IN OUT IN≅−()[]12/This formula has a maximum at V IN = 2V OUT , where I RMS = I OUT /2. This simple worst-case condition is com-monly used for design because even significant deviations do not offer much relief. Note that the capacitor manufacturer’s ripple current ratings are often based on 2000 hours of life. This makes it advisable to further derate the capacitor, or choose a capacitor rated at a higher temperature than required. Always consult the manufac-turer if there is any question.The selection of C OUT is driven by the required effective series resistance (ESR).芯天下--/8芯天下--/9340612faAPPLICATIO S I FOR ATIOW UUU 1. The V IN quiescent current is due to two components:the DC bias current as given in the electrical character-istics and the internal main switch and synchronous switch gate charge currents. The gate charge current results from switching the gate capacitance of the internal power MOSFET switches. Each time the gate is switched from high to low to high again, a packet of charge, dQ, moves from V IN to ground. The resulting dQ/dt is the current out of V IN that is typically larger than the DC bias current. In continuous mode, I GATECHG =f(Q T + Q B ) where Q T and Q B are the gate charges of the internal top and bottom switches. Both the DC bias and gate charge losses are proportional to V IN and thus their effects will be more pronounced at higher supply voltages.2. I 2R losses are calculated from the resistances of the internal switches, R SW , and external inductor R L . In continuous mode, the average output current flowing through inductor L is “chopped” between the main switch and the synchronous switch. Thus, the series resistance looking into the SW pin is a function of both top and bottom MOSFET R DS(ON) and the duty cycle (DC) as follows:R SW = (R DS(ON)TOP )(DC) + (R DS(ON)BOT )(1 – DC) (2)The R DS(ON) for both the top and bottom MOSFETs can be obtained from the Typical Performance Charateristics curves. Thus, to obtain I 2R losses, simply add R SW to R L and multiply the result by the square of the average output current.Other losses including C IN and C OUT E SR dissipative losses and inductor core losses generally account for less than 2% total additional loss.Thermal ConsiderationsIn most applications the LTC3406-1.2 does not dissipate much heat due to its high efficiency. But, in applications where the LTC3406-1.2 is running at high ambient tem-perature with low supply voltage, the heat dissipated may exceed the maximum junction temperature of the part. If the junction temperature reaches approximately 150°C,both power switches will be turned off and the SW node will become high impedance.To avoid the LTC3406-1.2 from exceeding the maximum junction temperature, the user will need to do some thermal analysis. The goal of the thermal analysis is to determine whether the power dissipated exceeds the maximum junction temperature of the part. The tempera-ture rise is given by:T R = (P D )(θJA )where P D is the power dissipated by the regulator and θJA is the thermal resistance from the junction of the die to the ambient temperature.The junction temperature, T J , is given by:T J = T A + T Rwhere T A is the ambient temperature.As an example, consider the LTC3406-1.2 with an input voltage of 2.7V, a load current of 600mA and an ambient temperature of 70°C. From the typical performance graph of switch resistance, the R DS(ON) at 70°C is approximately 0.52Ω for the P-channel switch and 0.42Ω for the N-channel switch. Using equation (2) to find the series resistance looking into the SW pin gives:R SW = 0.52Ω(0.44) + 0.42Ω(0.56) = 0.46ΩTherefore, power dissipated by the part is:P D = I LOAD 2 • R SW = 165.6mWFor the SOT-23 package, the θJA is 250°C/W. Thus, the junction temperature of the regulator is:T J = 70°C + (0.1656)(250) = 111.4°Cwhich is below the maximum junction temperature of 125°C.Note that at higher supply voltages, the junction tempera-ture is lower due to reduced switch resistance (R SW ).Checking Transient ResponseThe regulator loop response can be checked by looking at the load transient response. Switching regulators take several cycles to respond to a step in load current. When a load step occurs, V OUT immediately shifts by an amount equal to (∆I LOAD • ESR), where ESR is the effective series resistance of C OUT . ∆I LOAD also begins to charge or discharge C OUT , which generates a feedback error signal.芯天下--/10芯天下--/11Information furnished by Linear Technology Corporation is believed to be accurate and reliable.However, no responsibility is assumed for its use.
