FEATURES y y y y y y y Supply voltage range VDD 4.75V to 5.25V Driver supply voltage range VS 5.25V to 25V Low standby current (typical < 1A) 8-bit-parallel structure with memory function Bidirectional inputs and outputs TTL-compatible input levels with threshold hysteresis per channel, 8 channels capable of delivering y y y y y y Imax = 200mA simultaneously) Individual output short-circuit protection by This IC is designed for driving and controlling medium loads such as relays, lamps, LED, bus systems or other. It has got a bidirectional 8 bit-data bus and 8 identical power outputs. With its readback capability the status of the load can be determined. That makes easy diagnosis possible and lets the designer even control simple switches. Two versions are available: 910.32 in standard CMOS technology and 910.13 in SOI technology, which has high immunity against substrate currents. Integrated free wheeling diodes for inductive loads Thermal overload protection by switching off all outputs E910.32: - 40C to + 125C operating temperature, CMOS E910.13: - 40C to + 150C operating temperature, SOI SO24w package 8 high current outputs (Ron < 3, Imax = 350mA DESCRIPTION The IC is an 8 channel parallel power driver circuit (low side) with microcontroller compatible bidirectional dataports and output status monitoring.
