TPD2004F

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

Using independent four-channel inputs, this IC controls two high-side

and two low-side switches, making it possible to drive two squibs directly.

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

• Squib short diagnosis

• Squib drive MOSFET diagnosis

Chip select function allows for multi-channel structure to be materialized using minimum control lines.

Comes in a 24-pin SSOP surface mount package.

Supports embossed taping.
