Datasheet 4 Rev. 1.0, 2006-09-22 TLE 4275 V33 Block Description and Electrical Characteristics 3 Block Description and Electrical Characteristics 3.1 Voltage Regulator The output voltage VQ is controlled by comparing a portion of it to an internal reference and driving a PNP pass transistor accordingly. The control loop stability depends on the output capacitor CQ, the load current, the chip temperature and the poles/zeros introduced by the integrated circuit. To ensure stable operation, the output capacitor’s capacitance and its equivalent series resistor ESR requirements given in the table “Operating Range” have to be maintained. For details see also the typical performance graph “Output Capacitor Series Resistor ESRCQ vs. Output Current IQ”. Also, the output capacitor shall be sized to buffer load transients. An input capacitor CI is strongly recommended to buffer line influences. Connect the capacitors close to the IC terminals. Protection circuitry prevent the IC as well as the application from destruction in case of catastrophic events. These safeguards contain output current limitation, reverse polarity protection as well as thermal shutdown in case of overtemperature. In order to avoid excessive power dissipation that could never be handled by the pass element and the package, the maximum output current is decreased at input voltages above VI = 22 V. The thermal shutdown circuit prevents the IC from immediate destruction under fault conditions (e.g. output continuously short-circuited) by switching off the power stage. After the chip has cooled down, the regulator restarts. This leads to an oscillatory behaviour of the output voltage until the fault is removed. However, junction temperatures above 150 °C are outside the maximum ratings and therefore significantly reduce the IC lifetime. The TLE 4275 V33 allows a negative supply voltage. However, several small currents are flowing into the IC increasing its junction temperature. This has to be considered for the thermal design, respecting that the thermal protection circuit is not operating during reverse polarity conditions For details see typical performance graphs.

This signal might be used to reset a microcontroller during low supply voltage. In case the battery voltage is already lower than the buffered output voltage VQ of the voltage regulator, the reset circuit is supplied from the output “Q”, ensuring a defined reset switching threshold also at VI = 0 V. The Reset Output “RO” is held “low” down to an output voltage of VQ = 1 V, even if the input voltage VI is 0 V. Power-On Reset Delay Time: The power-on reset delay time td,PWR-ON allows a microcontoller and oscillator to start up. This delay time is the time period from exceeding the reset switching threshold VRT until the reset is released by switching the reset output “RO” from “low” to “high”. The power-on reset delay time td,PWR-ON is defined by an external delay capacitor CD connected to pin “D” which is charged up by the delay capacitor charge current ID,ch starting from VD = 0 V. For easy calculating the power-on reset delay time, a multiplier factor Fd,PWR-ON = td,PWR-ON / CD is specified. Hence, td,PWR-ON becomes: td,PWR-ON = Fd,PWR-ON / CD . (1) For a precise calculation consider also the delay capacitor’s tolerance. Undervoltage Reset Delay Time: Unlike the power-on reset delay time, the undervoltage reset delay td time considers a short output undervoltage event where the delay capacitor CD is assumed to be discharged to VD = VDST,lo only before the charging sequence restarts. Therefore, the undervoltage reset delay time td is defined by the delay capacitor charge current ID,ch starting from VD = VDST,lo and the external delay capacitor CD. For easy calculating the undervoltage reset delay time, a multiplier factor Fd = td / CD is specified. Hence, td becomes: td = Fd / CD . (2) For a precise calculation consider also the delay capacitor’s tolerance. Reset Reaction Time: The total reset reaction rime trr,total considers the internal reaction time trr,int and the discharge time trr,d defined by the external delay capacitor CD (see typical performance graph for details). Hence, the total reset reaction rime becomes: trr,total = trr,int + trr,d . (3) Reset Output “RO” Low for VQ ≥ 1 V: In case of an undervoltage reset condition reset output “RO” is held “low” for VQ ≥ 1 V, even if the input voltage VI is 0 V. This is achieved by supplying the reset circuit from the output capacitor. Datasheet 7 Rev. 1.0, 2006-09-22 TLE 4275 V33 Block Description and Electrical Characteristics Reset Output “RO”: The Reset Output “RO” is an open collector output requiring an external pull-up resistor to a voltage rail VIO. As the maximum Reset Output Sink Current IRO,max is limited, the minimum external pull-up resistor calculates: RRO,external,min = VIO / IRO,max. (4) e.g. +5 V Supply I Q Int.
