CS1112

Quad Power Output Driver

The CS1112 is a Power Output Driver. The IC incorporates four

protected DMOS low–side drivers designed to drive inductive and

resistive loads in an automotive environment. The outputs are

controlled by an 8–bit serial peripheral interface (SPI) or its associated

parallel input. Each output contains overcurrent protection, open load

detection, and inductive flyback clamps. The device is overvoltage

protected. Overcurrent and open load faults are reported over the SPI

port, and at the STATUS lead.

I/O Control

SPI communication is initiated by asserting CSB low. Data at the SI

lead is transferred on the rising edge of SCLK. The MSB is transferred

first. The outputs become active at the rising edge of CSB. Diagnostic

status bits are transferred out the SO lead at the falling edge of SCLK.

The SO lead is high impedance while CSB is high. An open drain

MARKING DIAGRAM

Each output independently detects shorts to V

while the output

is “on” and open load/short to ground while the output is “off”. The

fault register will be set if a fault occurs at the output. The fault register

will be reset if the fault condition is removed from the output. The

fault data is latched when CSB is asserted low.
