Overvoltage Protection Controllers

with Reverse Polarity Protection

5L/MAX4867

General Description

Features

The MAX4864L/MAX4865L/MAX4866L/MAX4867 over-

voltage protection controllers protect low-voltage sys-

tems 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 damage 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 components. An inter-

nal 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.
