BUS IC DC/DC CONVERTER MOTOR DRIVER IC RIPPLE COUNTER DRIVER IC I/O IC SENSOR IC SENSOR INTERFACE IC Low side driver 8x, serial ÿ Low side driver 8x, parallel LCD controller ÿ Low side driver (8 channel, parallel interface) FEATURES APPLICATION PINNING Driver for: ÿ Supply voltage range VDD 4.75V to 5.25V ÿ Driver supply voltage range VS 5.25V to 25V ÿ Relays ÿ Low standby current (typical < 1µA) ÿ Lamps / LEDs ÿ 8-bit-parallel structure with memory function ÿ DC and stepper motors ÿ Bidirectional inputs and outputs ÿ Bus systems ÿ TTL-compatible input levels with threshold ÿ E910.32 | 13 hysteresis DESCRIPTION 8 high current outputs (Ron < 3Ω, Imax = 350mA The IC is an 8 channel parallel power driver circuit (low side) with per channel, 8 channels capable of delivering microcontroller compatible bidirectional dataports and output Imax = 200mA simultaneously) status monitoring. switching off the corresponding output This IC is designed for driving and controlling medium loads such ÿ Integrated free wheeling diodes for inductive loads as relays, lamps, LED, bus systems or other. It has got a bidirec- ÿ Thermal overload protection by switching off tional 8 bit-data bus and 8 identical power outputs. ÿ Individual output short-circuit protection by all outputs ÿ E910.32: – 40°C to + 125°C operating temperature, CMOS With its readback capability the status of the load can be deter- ÿ E910.13: – 40°C to + 150°C operating temperature, SOI mined. That makes easy diagnosis possible and lets the designer ÿ SO24w package 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.
