Datasheet

Texas Instruments Incorporated today introduced the TPIC71004-Q1 four-channel squib driver for airbag deployment, providing an optimized integrated catalog device that is reliable and cost-effective. The four-channel squib device is part of a family of multi-squib driver devices that allow flexibility for airbag designers to quickly and cost-effectively scale their design to the needs of their system. 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.

Key features and benefits
• Designed for safety: The TPIC71004-Q1 is a four-channel squib driver. Each channel consists of a high side and low side switch with independent control logic for protection against inadvertent airbag deployment.
• Protection: Built-in diagnostics for loop monitoring and reporting, as well as two logic inputs to provide independent safety logic for enabling/disabling deployment.
• Design flexibility: 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 for complete design flexibility, regardless of the number of channels required.

Availability, packaging and pricing
The TPIC71004-Q1 is available for ordering now from TI and its authorized distributors. It is offered in a thermally-enhanced 48-Pin TSSOP DCA PowerPad™ package and is qualified to automotive grade.
