特性
- Four-channel high-side and low-side 2.0 A FET switches
- Externally adjustable FET current limiting
- Adjustable current limit range: 0.8 A to 2.0 A
- Individual channel current limit detection with timing duration measurement, communicated via SPI
- 8-bit SPI for diagnostics and FET switch activation
- Diagnostics for high-side safing sensor status
- Resistance and voltage diagnostics for squibs
- Squib driver IC capability to be used for cross-coupled driver firing application (allows high- and low-side FET switches to be located on separate squib driver ICs)
