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

voltage of

V

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.
