TLE42794
Overview
input voltage) can be monitored, an under-voltage condition is indicated by setting the comparator’s output to low.
If pull-up resistors are desired at the outputs of the reset and the sense comparator, the TLE42694 with integrated
pull-up reistors can be used instead of the TLE42794.
Dimensioning Information on External Components
The input capacitor C_I is recommended for compensation of line influences. The output capacitor C_Q 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
