MAX14562

36V-Capable Overvoltage Protector with Regulated Output Voltage

36V-Capable Overvoltage Protector with Regulated Output Voltage Addresses a Variety of Portable Consumer Electronics


Please check latest availability status for a specific part variant.

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 (VPROV) threshold, the output tracks the input minus the voltage drop (RON × 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 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.
