... MOSFET quickly and disconnects the input from the load. Undervoltage/Overvoltage Detection—MIC2588 The MIC2588 has “UV” and “OV” input pins. These pins can be used to detect input supply rail undervoltage and overvoltage conditions. Undervoltage lockout prevents energizing the load until the supply input is stable and within tolerance ...

... MIC2588/MIC2594 the OFF pin falls below its V threshold value, or the part OFFL turns off due to a fault. Should either event occur, the GATE pin is immediately pulled low and will remain low until the ON pin once again exceeds its V ONH turn-on and turn-off points are set using the resistor divider R1, R2, and R3 as shown in the “ ...

... V IN(MAX) DD The second breakdown voltage criterion that must be met is the gate-source voltage. For the MIC2588/MIC2594, the gate of the external MOSFET is driven maximum of 11V above VEE. This means that the external MOSFET must be chosen to have a gate-source breakdown voltage of 12V or more; 20V is recommended. Most power MOSFETs with a 20V gate-source voltage rating have a 30V drain-source breakdown rating or higher ...
