CS1107
Single Relay Driver IC
Description
This ASIC provides up to 350mA 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 protec-
tion 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.
