Description
The two power comparators can swit ch magnet s, motors or oth er loads eith er 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 c omm on-mo de in put
V
voltage range from 0 V to approx . the value of
V
voltage of
. To obtain low saturation voltages at the sink circuit, the drive circuit of the
S
and in a maximum input differential
S
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.
