High side drivers

The device embeds fully-protected high-side drivers for use outside of the car-radio module.

HSD1, HSD2

These high side driver outputs have short circuit protections consisting of current limit and

independent thermal shutdown. If the local die temperature exceeds the thermal shutdown

detection threshold, the output is disabled. The thermal shutdown circuitry has hysteresis

such that the output is enabled only after the die temperature falls below the thermal

shutdown disable threshold. Thermal shutdown on any one output doesn't directly disable

any other circuitry.

HSD1 and HSD2 are protected from shorts to ground and shorts to battery (0-18 V) during a

loss of car-radio module battery.
