Driver diagnostic

9.3.1

Thermal protection

Each solenoid channel has a dedicated temperature sensor that continuously monitors the

temperature of the PowerMOS.

In case the shutdown temperature Tsd is reached the related channel is turned off and the

dedicated diagnostic bits are set. t_sdl_x is the bit that latches the thermal shut down and it

is cleared after sending dedicated SPI to clear the bit, t_sd_x is the other thermal shut down

bit and once it is set by thermal shut down condition it is cleared only when the Tj decreases

below the thermal shut down threshold (hysteresis). If the microcontroller, when the device
