CS1107
Single Relay Driver IC
This ASIC provides up to 350 mA of drive current for driving a
relay. On–chip diagnostic features include open and short circuit
detection in the on state, duty cycle current limit control, and thermal
shutdown. Faults are reported on the Fault lead. Fault is an active–low
output. An on–chip zener provides protection from flyback pulses
from the relay. Internal pull–down circuitry is provided to ensure the
output pin turns off when the Control pin is floating.
