An input voltage of up to 45 V is regulated to an output voltage of 5 V. The integrated reset as well as several protection circuits, combined with a wide operating temperature range offered by the TLE4699 make it suitable for supplying microprocessor systems in automotive environments. The early warning function supervises the voltage at pin SI. Modifying the reset threshold is possible by an optional resistor divider. The TLE4699 is available in a PG-DSO-14 package which makes it pin-compatible to the TLE4299 as well as in a small thermally enhanced PG-SSOP-14 EP exposed pad package.

Data Sheet 11 Rev. 1.0, 2010-11-30 TLE4699 Voltage Regulator 5 Voltage Regulator 5.1 Description 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. Saturation control as a function of the load current prevents any oversaturation of the pass element. 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 ““Functional Range” on Page 10 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 not needed for the control loop stability, but 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 behavior of the output voltage until the fault is removed. However, a junction temperature above 150 °C is outside the maximum rating and therefore reduces the IC lifetime. The TLE4699 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 condition.

This signal might be used to reset a microcontroller during a low supply voltage condition. Power-On Reset Delay Time The power-on reset delay time td,PWR-ON allows a microcontroller and oscillator to start up. This delay time is the time period from exceeding the upper reset switching threshold VRT,hi 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. In case a power-on reset delay time td,PWR-ON different from the value for CD = 100nF is required, the delay capacitor’s value can be derived from the specified value given in Item 8.2.15: t d,PWR-ON C D = ----------------------------------- × 100 nF t d,PWR-ON,100nF with td,PWR-ON: Desired power-on reset delay time td,PWR-ON,100nF: Power-on reset delay time specified in Item 8.2.15 CD: Delay capacitor required The formula is valid for CD ≥ 10 nF.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 starts. 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. A delay capacitor CD for a different undervoltage reset delay time as specified in Item 8.2.14 can be calculated similar as above: td C D = ---------------- × 100 nF t d,100nF with td: Desired reset delay time td,100nF: Reset delay time specified in Item 8.2.14 CD: Delay capacitor required The formula is valid for CD ≥ 10 nF.For a precise calculation consider also the delay capacitor’s tolerance. • • • Data Sheet 20 Rev. 1.0, 2010-11-30 TLE4699 Reset Function Reset Reaction Time In case the output voltage of the regulator drops below the output undervoltage lower reset threshold VRT,lo, the delay capacitor CD is discharged rapidly. Once the delay capacitor’s voltage has reached the lower delay switching threshold VDST,lo, the reset output RO will be set to “low”. Additionally to the delay capacitor discharge time trr,d an internal time trr,int applies. Hence the total reset reaction time trr,total becomes: t rr,total = t rr,int + t rr,d with • • • trr,total: total reset reaction time trr,int: Internal reset reaction time; see Item 8.2.16 trr,d: Delay capacitor discharge time. For a capacitor CD different from the value specified in Item 8.2.17, see typical performance graphs. Reset Output “RO” The reset output “RO” is an open collector output with an integrated pull-up resistor. In case a lower-ohmic “RO” signal is desired, an external pull-up resistor to the output “Q” can be connected. Since the maximum “RO” sink current is limited, the optional external resistor RRO,ext must not below as specified in Item 8.2.8. 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. Reset Adjust Function The undervoltage reset switching threshold can be adjusted according to the application’s needs by connecting an external voltage divider (RADJ1, RADJ2) at pin “RADJ”. For selecting the default threshold connect pin “RADJ” to GND. The reset adjustment range is given in Item 8.2.6. When dimensioning the voltage divider, take into consideration that there will be an additional current constantly flowing through the resistors. With a voltage divider connected, the reset switching threshold VRT,new is calculated as follows R ADJ, 1 + R ADJ, 2 V RT,new = V RADJ,th × ----------------------------------------R ADJ, 2 with • • • VRT,new: Desired reset switching threshold.
