Functional Description

The TLE 4299 is a monolithic voltage regulator with fixed 5-V output, supplying loads up
to 150 mA. It is especially designed for applications that may not be powered down while
the motor is off. It only needs a quiescent current of typical 65

mA. In addition the

TLE 4299 GM includes an inhibit function. When the inhibit signal is removed, the device
is switched off and the quiescent current is less than 1
of the

m-controller, the device supplies a reset signal. The reset delay t ime is selected

mA. To achieve proper operation

application-specific by an external delay capacitor. The reset threshold is adjustable. An
early warning signal supervises the voltage at pin SI. The TLE 4299 is pin-compatible to
the TLE 4269 and functional similar with the additional inhibit function. The TLE 4299 is
designed to supply microcontroller systems even under automotive environment
conditions. Therefore it is protected against overload, short circuit and over temperature.

The internal control circuit achieves a 5 V output voltage with a tolerance of

The device includes a power on reset and an under voltage reset function with adjustable
reset delay time and adjustable reset switching threshold as well as a sense control/early
warning function. The device includes an inhibit functi on to disable it whe n the ECU is
not used for example while the motor is off.

the output current is reduced (SOA protection).

Reset

The power on reset feature is necessary for a defined start of the microprocessor when
switching on the application. For the reset delay time after the output voltage of the
regulator is above the reset threshold, the reset signal is set High again. The reset delay
time is defined by the reset delay capacitor

The under-voltage reset circu itry supervises the output voltag e. In case
below the reset threshol d t he rese t output is set LOW afte r th e re set reac tio n ti me. The
reset LOW signal is generated down to an output voltage
reaction time and the reset delay time is defined by the capacitor value.

Early Warning

The early warning function compares a voltage defined by the user to an internal
reference voltage. Therefore the supervised voltage has to be scaled down by an
external voltage divide r in order to compare it to the internal sense thresho ld of typical

1.35 V. The sense output pin is set low, when the voltage at SI falls below this threshold.
A typical example wh ere the circuit c an be used is to supervise t he input voltage
