TLE 4202 B
Bipolar IC
P-TO220-7-1
Type
TLE 4202 B
Ordering Code
Q67000-A8225
Package
P-TO220-7-1
Description
The two power comparators can switch magnets, motors or other loads either by being
separated from each other or by being combined to a full-bridge circuit. The IC is
designed for application in motor vehicles. It can be applied at package temperatures
between – 40 °C and 130 °C.
The IC contains two amplifiers featuring a typical open-loop voltage gain of 80 dB at
500 Hz.
The input stages are PNP differential amplifiers thus resulting in a common-mode input
voltage range from 0 V to approx. the value of V_S and in a maximum input differential
voltage of V_S. To obtain low saturation voltages at the sink circuit, the drive circuit of the
sink transistor is connected to the supply voltage. An SOA protective circuit protects the
IC against ground short-circuits. At chip temperatures above approx. 160 °C the source
transistors are turned off.
