he ZCC5060high-side protection controller providesintelligentcontrol of a high-side N-channel MOSFETduring normal on/off transitions and fault conditions.In-rush current iscontrolled by the nearly constantrise time of the output voltage.
A POWERGOODoutput indicates when the output voltage reaches theinput voltage and the MOSFET is fully on. InputUVLO (with hysteresis) is provided as well asprogrammable input OVP. An enable input providesremote on or off control. The programmable UVLO input can be used as second enable input for safetyredundancy. A single capacitor programs the initialstart-up VGs fault detection delay
time, the transitionV fault detection delay time, and the continuous over-current Vps fault detection delay time. When adetected fault condition persists longer than theallowed fault delay time, the MOSFET is latched offuntil either the enable input or the UVLO input istoggled low and then high.
