简 介: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. Features Serial Input Bus Two Squib Outputs Low– and High–Side Control Monitors – Squib Resistance – Short to Ground or Battery – Battery Potential – Firing Potential Safing Sensor Detection 60 V Peak Transient Voltage
