Adjustable Overvoltage Protector

with High Accuracy

7/MAX14528

General Description

Features

The MAX14527/MAX14528 overvoltage protection

♦ Input Voltage Protection Up to +28V

devices feature a low 100mΩ (typ) R

internal FET

♦ Preset Internal 2ꢀ.5 ꢁccurate ꢂVꢃꢂ ꢄTresTolꢅs

.ꢀ7.V (MꢁX14.27)

and protect low-voltage systems against voltage faults

up to +28V. When the input voltage exceeds the over-

voltage threshold, the internal FET is turned off to pre-

vent damage to the protected components.

6ꢀ76V (MꢁX14.28)

♦ ꢁꢅjustable ꢂvervoltage Protection ꢄrip ꢃevel

The overvoltage protection threshold can be adjusted

with optional external resistors to any voltage between

4V and 8V. With the OVLO input set below the external

OVLO select voltage, the MAX14527/MAX14528 auto-

matically choose the internal 2.5ꢀ accurate trip

thresholds. The internal overvoltage thresholds (OVLO)

are preset to 5.75V typical (MAX14527) or 6.76V typical

(MAX14528). The MAX14527/MAX14528 are also

protected against overcurrent events with an internal

thermal shutdown.

♦ 8-Pin ꢄDFN (2mm x 2mm) Package

♦ -40°C to +8.°C ꢂperating ꢄemperature Range

The MAX14527/MAX14528 are offered in a small, 8-pin

TDFN-EP package and operate over the -40°C to

+85°C extended temperature range.
