Description

The TLE 42694 is a monolithic integrated low dropout voltage regulator, especially designed for automotive applications. An input voltage up to 45 V is regulated to an output voltage of 5.0 V. The component is able to drive loads up to 150 mA. It is short-circuit proof by the implemented output current limitation and has an integrated overtemperature shutdown. A reset signal is generated for an output voltage VQ,rt of typically 4.65 V. This threshold can be decreased by an external resistor divider. The power-on reset delay time can be programmed by the external delay capacitor. The additional sense comparator provides an early warning function: Any voltage (e.g. the input voltage) can be monitored, an under-voltage condition is indicated by setting the comparator’s output to low. The reset and sense output are internally connected to the output Q via a pull-up resistor. If these integrated resistors are not desired, the TLE42794 can be used instead of the TLE42694.

Data Sheet 3 Rev. 1.1, 2008-10-07 TLE42694 Overview Dimensioning Information on External Components The input capacitor CI is recommended for compensation of line influences. The output capacitor CQ is necessary for the stability of the control loop. Circuit Description The control amplifier compares a reference voltage to a voltage that is proportional to the output voltage and drives the base of the series transistor via a buffer. Saturation control as a function of the load current prevents any oversaturation of the power element. The component also has a number of internal circuits for protection against:

Overload
Overtemperature
Reverse polarity

5.1 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. Th e control loop stability depe nds on the outpu t capacitor CQ, the load current, the chip temperature and the poles/zeros introduced by the integr ated 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 9 have to be maintained. For details see also the typical performance graph “Output Capacitor Series Resistor ESR(CQ) versus Output Current IQ” on Page 14. As the output capacitor also has to buffer load steps it should be sized according to the application’s needs. An input capacitor CI is strongly recommended to compensate line influences. Connect the capacitors close to the component’s terminals. A protection circuitry prevents the IC as well as the application from destruction in case of catastrophic events. These safeguards contain an output current limitation, a reverse polarity protection as well as a 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 imme diate 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 remo ved. However, junction temperatures above 150 °C are outside the maximum ratings and therefore significantly reduce the IC’s lifetime. The TLE 42694 allows a negative supply voltage. In this fault condition, 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.

5.3 Reset Function

The reset function provides several features: Output Undervoltage Reset: An output undervoltage condition is indicated by setting the Reset Output RO to “low”. This signal might be used to reset a microcontroller during low supply voltage. Power-On Reset Delay Time: The power-on reset delay time trd allows a microcontoller and oscillator to start up. This delay time is the time frame 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 trd is defined by an external delay capacitor CD connected to pin D charged by the delay capacitor charge current ID,ch starting from VD = 0 V. If the application needs a power-on reset delay time trd different from the value given in Item 5.3.8, the delay capacitor’s value can be derived from the specified values in Item 5.3.8 and the desired power-on delay time: CD trd new, trd with

CD: capacitance of the delay capacitor to be chosen
trd,new: desired power-on reset delay time
trd: power-on reset delay time specified in this datasheet For a precise calculation also take the delay capacitor’s tolerance into consideration. Reset Reaction Time: The reset reaction time avoids that short undervoltage spikes trigger an unwanted reset “low” signal. The reset reaction rime trr 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 time becomes: trr trd int, trr d,+= with
trr: reset reaction time
trr,int: internal reset reaction time
trr,d: reset discharge Optional Reset Output Pull-Up Resistor RRO,ext: The Reset Output RO is an open co llector output with an integrated pull-up resistor. To improve the EMC behaviour of the component, an external pull-up resistor to the output VQ can be added. In Table “Electrical Characteristics Reset Function” on Page 21 a minimum value for the external resistor RRO,ext is given.

Block Description and Electrical Characteristics Data Sheet 18 Rev. 1.1, 2008-10-07 Reset Adjust Function The undervoltage reset switching threshold can be adjuste d according to the application’s needs by connecting an external voltage divider (RADJ1, RADJ2) at pin RADJ. For selecting the defa ult threshold connect pin RADJ to GND. 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: VRT new, RADJ 1, R+ ADJ 2, RADJ 2, with

VRT,new: the desired new reset switching threshold
RADJ1, RADJ2: resistors of the external voltage divider

TLE42694 specifications and overview.

Summary

Low Dropout Fixed Voltage Regulator Rev. 1.1, October 2008

Description

The TLE 42694 is a monolithic integrated low dropout voltage regulator, especially designed for automotive applications. An input voltage up to 45 V is regulated to an output voltage of 5.0 V. The component is able to drive loads up to 150 mA. It is short-circuit proof by the implemented output current limitation and has an integrated overtemperature shutdown. A reset signal is generated for an output voltage VQ,rt of typically 4.65 V. This threshold can be decreased by an external resistor divider.
