Overview

www.DataSheet4U.com Freescale Semiconductor Technical Data MC33797 Rev 2.0, 07/2005 Four Channel Squib Driver IC The Four Channel Squib Driver IC is a complete squib diagnostic and deployment interface for use in automotive air bag modules.

Key Features

  • are incorporated to provide fail-safe operation. The device contains a serial peripheral interface (SPI) compatible 8-bit interface to allow microprocessor control. The device has the capability to be used in a standard four-channel squib driver IC or in a cross-coupled state with the high- and low-side squib drivers located on separate squib driver ICs. Both the high- and low-side output drivers are protected against temporary shorts to battery or ground. The current limit threshold is set by a.
