2-channel Squib Driver for Air Bags
Manufactured through the Bi-CMOS-DMOS process, this 2-channel squib
drive IPD is designed for use in SRS electronic system air bags.
Features
z Using independent four-channel inputs, this IC controls two high-side
and two low-side switches, making it possible to drive two squibs directly.
z Incorporates various diagnostic functions (analog multiplexer outputs):
• Squib short-to-battery diagnosis
• Squib short-to-ground diagnosis
• Squib open-circuit diagnosis
• Safing sensor-ON fault diagnosis
• High-redundancy, upstream arrangement for safing sensor
Weight: 0.29g (typ.)
• Squib short diagnosis
• Squib drive MOSFET diagnosis
z Chip select function allows for multi-channel structure to be materialized using minimum control lines.
z Comes in a 24-pin SSOP surface mount package.
z Supports embossed taping.
