Key Features

Two-Channel Squib Drivers For Airbag Application
Loop Diagnostics Monitor and Reporting
Two Logic Inputs Providing Independent Safety Logic for
Enabling/Disabling Deployment
Two Independent Thermally Protected High-Side Drivers that Can
Source Deployment or Diagnostic Current Level to Each Squib Load
Two Independent Avalanche Voltage and Thermally Protected Low-Side
Drivers that can Sink Deployment or Diagnostic Current Level
from Each Squib Load
Each Output Capable of 1.2 A/1.75 A Firing Current for Typical 2 ms/0.5 ms
SPI Slave Interface for Serial Bus Communication with Parity Check
Firing VZx Voltage Range 10V to 35V, Transients up to 40 V
Programmable Firing Time up to 8.2 ms
Common Load Current Settings for All Deployment Loops, Using Registers
Individual Firing Current Timer Limit Set for Each Deployment Loop, Using Registers
Firing Current Timer to Monitor Firing Current Over Deployment Time for Each Deployment Loop
Independent Switch Control for Both High- And Low-Side Switches
Diagnostic Mode for Fault Checking
Internal Fault Monitoring for Safe Operation
Multiplexable Output Buffer for Analog Voltage Measurements
Use of External Clamping Devices on Squib Pins is Not Required to Protect the
Deployment ASIC Against Substrate Injection Effects During Deployment Due to Dynamic
Shorts to Ground
External Pin Connection to the Microprocessor ADC Supply for Ratio-Metric Squib
Resistance Measurement
40-V Pin Capability on All Pins (Except GNDx, AGND, DGND, VCC5, VDDIO, AMX_OUT)
Operating Ambient Temperature Range: –40°C to 105°C
Thermally Enhanced 48-Pin TSSOP DCA PowerPad Package
APPLICATIONS
