CS2082EDWR20

Specialized ICS Overview

The CS2082EDWR20 is a dual airbag deployment ASIC designed to control and monitor two independent firing loops. It features low- and high-side drivers with current limiting, enabling precise squib actuation. Communication occurs via an SPI interface up to 2.0 MHz, incorporating frame error detection for data integrity. The device includes comprehensive diagnostics such as squib resistance measurement, short-to-ground/battery detection, and safing sensor closure monitoring. Electrical characteristics specify operation within VCC (4.75–5.25 V), VBAT (9.0–18 V), and VRES (8.0–30 V) ranges, with thermal shutdown protection at 150–210°C.
