• Description: 1-A DC Motor Driver
• Manufacturer: SIEMENS [Siemens Semiconductor Group]

guarded against ground shorts by an SOA-protective circuit. The output transistors are
turned off if the chip temperature exceeds approx. 160 C. The IC can be turned off by
an inhibit input, which very much reduces current consumption.
Circuit Description
The IC contains two amplifiers with typical open-loop gain of 80 dB at 500 Hz.
The input stages consist of PNP-differential amplifiers. This produces a common-mode
input range of 0 V to nearly
