LOW SIDE INJECTOR DRIVER
to control various automotive loads such as injectors,
solenoids, lamps, relays and unipolar stepper motors. Each
driver includes off and on state open load detection, short
circuit protection and diagnostics. The injector drivers are
individually controlled through the ON/OFF SPI input
command
and parallel control of the output state is determined by the
logical OR of the SPI serial bit and the DINx parallel input
pins. All four outputs are disabled when the OUTEN input pin
is high regardless of the state of the SPI control bit or the
state of the DINx pin. All four injector drivers are not affected
by the selection of the gate driver’s three modes of operation
(Ignition Mode, General Purpose Mode, V10 mode).

ON /OFF CONTROL COMMAND
a 16-bit serial stream of data is entered into the SI pin. The
first 4 bits of the control word are used to identify the On / Off
Command. Bit 0 through bit 3 of the ON/OFF Control
Command turn ON or OFF the specific output driver.
INJECTOR DRIVER FAULT COMMANDS
programmed by the SPI LSD Fault Command. Bit 8 through
11 determine the type of short circuit protection to be used,
bits 0 through 7 set the open load strategy.
strategies utilize current limiting as an active element to
protect the output driver from failure.The
options are used to enhance the short circuit protection
strategy of the Injector drivers. The timer protection scheme
uses a low duty cycle in the event of a short-circuit. The
