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.
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
