TPIC71008 Eight Channel Squib Driver

Texas Instruments TPIC71008 Eight-Channel Squib Driver is for airbags deployment in automotive applications. Each channel consists of a high side and low side switch with independent control logic for protection against an accidental deployment. Both the high and the low side switches have an internal current limit and over-temperature protection. The IC registers are used for eight-channel configuration, control, and status monitoring. The high and the low side switches of the Texas Instruments TPIC71008 are turned on only if the proper configuration sequence is used to prevent accidental deployment. Two independent arming/saving inputs are active, and multiple inputs to the deployed controller logic are at the correct level. The registers are programmed using a serial communications interface.
