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
output, (STATUS) reports a fault (short to V
PWR
, GND, or open load)
has occurred at one or more of the outputs.
Protection
Each output independently detects shorts to V
PWR
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.
If an overcurrent condition or short circuit to V
BATT
occurs, the
output goes into a low duty cycle mode for the duration of the fault.
The outputs are disabled during an overvoltage or undervoltage
condition.
