MAX14588

1A Adjustable Overcurrent and Overvoltage

Protector with High Accuracy

General Description

The MAX14588 adjustable overvoltage and overcurrent

protection device is ideal for protecting systems against

positive and negative input voltage faults up to ±40V, and

The adjustable overvoltage range is between 6V and 36V,

while the adjustable undervoltage range is between 4.5V

and 24V. The overvoltage lockout (OVLO) and undervoltage

lockout (UVLO) thresholds are set using optional external

resistors. The factory preset internal OVLO threshold is 33V

(typ), and the preset internal UVLO threshold is 19V (typ).

The MAX14588 also features programmable current-limit

protection up to 1A. The device can be set for autoretry,

latch-off, or continuous fault response when an overcur-

rent event occurs. Once current reaches the threshold, the

MAX14588 turns off after 21ms (typ) blanking time, and

stays off during the retry period when set to autoretry mode.

The device latches off after the blanking time when set to

latch-off mode. The device limits the current continuously

when set to continuous mode. The MAX14588 also features

reverse current and thermal shutdown protection.

The MAX14588 is available in a small, 16-pin (3mm x 3mm)

TQFN package. The MAX14588 operates over the -40°C to

+125°C extended temperature range.
