Configuration and status diagnosis are done via SPI. An 8 bit serial peripheral interface (SPI) is used. The SPI can
be used in daisy chain configuration.
The device provides a current sense signal per channel that is multiplexed to the diagnosis pin IS. It can be
enabled and disabled via SPI commands. An over load and over temperature flag is provided in the SPI diagnosis
word. A multiplexed switch bypass monitor provides short-circuit to
The SPOC - BTS5662E provides a fail-safe feature via a limp home input pin.
The power transistors are built by N-channel vertical power MOSFETs with charge pumps. The device is
monolithically integrated in SMART technology.
