Four Channel Squib Driver IC
The Four Channel Squib Driver IC is a complete squib diagnostic and
deployment interface for use in automotive air bag modules.
Extensive diagnostics and system control features are incorporated
to provide fail-safe operation. The device contains a serial peripheral
interface (SPI) compatible 8-bit interface to allow microprocessor
control.
The device has the capability to be used in a standard four channel
squib driver IC or in a cross-coupled state with the high and low side
squib drivers located on separate squib driver ICs. Both the high and
low side output drivers are protected against temporary shorts to
battery or ground. The current limit threshold is set by an external
resistor. This device is powered by SMARTMOS technology.
Features
Four channel high side and low side 2.0 A FET switches
Externally adjustable FET current limiting
Adjustable current limit range: 0.8 to 2.0 A
Individual channel current limit detection with timing duration
measurement, communicated via the SPI
8-Bit SPI for diagnostics and FET switch activation
Diagnostics for high side safing sensor status
Resistance and voltage diagnostics for squibs
Squib driver IC capability to be used for cross-coupled driver firing
application (allows high and low side FET switches to be located
on separate squib driver ICs)
