TI expands automotive safety portfolio with airbag squib driver family

May 13, 2011 // By Christoph Hammerschmidt
As part of its multi-squib driver chip family for airbag deployment, Texas Instruments has introduced the TPIC71004-Q1 four-channel squib driver, providing a cost-optimized integrated catalog device. The family of multi-squib driver devices allows flexibility for airbag designers to quickly and cost-effectively scale their design to the needs of their system, TI says.

As part of its multi-squib driver chip family for airbag deployment, Texas Instruments has introduced the TPIC71004-Q1 four-channel squib driver, providing a cost-optimized integrated catalog device. The family of multi-squib driver devices allows flexibility for airbag designers to quickly and cost-effectively scale their design to the needs of their system, TI says.

Each channel of the TPIC71004-Q1 four-channel squib driver consists of a high side and low side switch with independent control logic for protection against inadvertent airbag deployment. Built-in diagnostics for loop monitoring and reporting, as well as two logic inputs provide independent safety logic for enabling/disabling deployment.

When coupled in pairs or with TI's TPIC71002-Q1 two-channel squib driver, allows for complete design flexibility, regardless of the number of channels required. 

The TPIC71004-Q1 is available for ordering now. It is offered in a thermally-enhanced 48-Pin TSSOP DCA PowerPad package and is qualified to automotive grade. The TPIC71004-Q1 is priced at $3.25 in quantities of 100. Samples, evaluation modules and application notes are available.

The family joins TI's product portfolio and comprehensive support network for automotive safety system designs encompassing airbags, braking, stability control, tire pressure monitoring systems and electronic power steering.
