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

TI's family of automotive safety products offers full scalability. The four-channel device, when coupled in pairs or with TI's TPIC71002-Q1 two-channel squib driver, allows further design flexibility.

The four-channel squib device is part of a family of multi-squib driver devices that the company claims allow flexibility for airbag designers to quickly and cost-effectively scale their design to the needs of their system.

The TPIC71004-Q1 is available for now in a thermally-enhanced 48-pin TSSOP DCA PowerPad package and is qualified to automotive grade. The TPIC71004-Q1 is priced Rs.145.09 ($3.25) in quantities of 100. Samples and evaluation modules are available.
