CS2082/D

CS2082

Dual Airbag

Deployment ASIC

The CS2082 controls and monitors two airbag firing loops. The

independent firing loops are low– and high–side controlled. Device

communication is through a Serial Peripheral Interface (SPI) port, and

includes frame error detection circuitry for data reliability.

Diagnostics include squib resistance measurement and continuous

monitoring for shorts to ground, shorts to battery, and for open loops.

The high– and low–side drivers can be individually activated to

guarantee function and to identify shorts between firing loops.

Additional features include power on reset, overtemperature

protection, a charge pump, high–side safing sensor closure detection,

an analog multiplexer, a monitor to ensure battery potential, and a

programmable monitor to ensure firing potential.
