Description

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 output-voltage (V_PROV) threshold, the output tracks the input minus the voltage drop (R_ON × I_LOAD) across the pass FET. If the input exceeds V_PROV, the output is regulated to V_PROV. If the input rises further and exceeds the overvoltage lockout cutoff threshold (V_OVLO), the output is disconnected from the input.

A low resistance 160mΩ (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.

The MAX14562 is specified over the extended -40°C to +85°C temperature range and is available in 8-pin TDFN (2mm x 2mm) and 6-pin SC70 (2mm x 2.2mm) packages.
