The device is housed in a Multiwatt 15 pin pack- Each output has a dedicated overcurrent protec- _age. An internal zener diode connected between tion and the device is overvoltage protected. The the source and the drain of each power DMOS Status pin provides the microprocessor with the allows a fast recirculation with a clamping voltage fault status feedback. higher than 6OV.
