Overvoltage Protection Controllers

with Reverse Polarity Protection

General Description

Features

The MAX4864L/MAX4865L/MAX4866L/MAX4867/

MAX4865/MAX4866 overvoltage protection controllers

protect low-voltage systems against high-voltage faults

up to +28V, and negative voltages down to -28V. These

devices drive a low-cost complementary MOSFET. If the

input voltage exceeds the overvoltage threshold, these

devices turn off the n-channel MOSFET to prevent dam-

age to the protected components. If the input voltage

drops below ground, the devices turn off the p-channel

MOSFET to prevent damage to the protected compo-

nents. An internal charge pump eliminates the need for

external capacitors and drives the MOSFET GATEN for

a simple, robust solution.

♦ Overvoltage Protection Up to +28V

♦ Reverse Polarity Protection Down to -28V

♦ Preset Overvoltage (OV) Trip Level (7.4V, 6.35V,

5.8V, 4.65V)

♦ Drive Low-Cost Complementary MOSFET

♦ Internal 50ms Startup Delay

♦ Internal Charge Pump

♦ 8.5µA Standby Current (In UVLO Mode)

♦ 0.4µA Shutdown Current

♦ Overvoltage Fault FLAG Indicator

♦ 6-Pin (2mm x 2mm) µDFN and 6-Pin SOT23

The overvoltage thresholds are preset to +7.4V

(MAX4864L), +6.35V (MAX4865L), +5.8V (MAX4866L),

and +4.65V (MAX4867). When the input voltage drops

below the undervoltage lockout (UVLO) threshold, the

devices enter a low-current standby mode (8.5µA). Also in

shutdown (EN set to logic-high), the current is reduced fur-

ther (0.4µA). The MAX4864L/MAX4865L/MAX4866L have

a +2.85V UVLO threshold, and the MAX4867 has a +2.5V

UVLO threshold. The MAX4865/MAX4866 have a 4.15V

UVLO threshold.

In addition, a 15kV ESꢀ protection is provided to the

input when bypassed with a 1µF capacitor to ground. All

devices are offered in a small 6-pin SOT23 and a 6-pin,

2mm x 2mm µꢀFN package, and are specified for

operation over the -40°C to +85°C temperature range.
