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 d B at 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 VS and in a maximum input differential voltage of VS. 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.
