36V-Capable Overvoltage Protector with
Regulated Output Voltage
Features
The MAX14562 protects valuable consumer circuits
against voltage faults of up to +36V. This robust protection is implemented in a three-step scheme for a superior
result. If the input is below the preset regulated outputvoltage (VPROV) threshold, the output tracks the input
minus the voltage drop (RON x ILOAD) across the pass
FET. If the input exceeds VPROV, the output is regulated
to VPROV. If the input rises further and exceeds the overvoltage lockout cutoff threshold (VOVLO), the output is
disconnected from the input.

A low resistance 160mI (typ) FET is integrated in the
MAX14562, effectively reducing the component count
and application footprint. The MAX14562 also features
thermal shutdown protection against a short-circuit
event.
