TPD2004F 2-channel Squib Driver

TPD2004F TOSHIBA Intelligent Power Device Silicon Monolithic Power MOS IC 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 z Using independent four-channel inputs, this IC controls two high-side and two low-side switche.

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 .
