The MAX14588 adjustable overvoltage and overcurrent protection device is ideal for protecting systems against positive and negative input voltage faults up to ±40V, and feature low 190mΩ (typ) R_ON integrated FETs.

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 overcurrent 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.

Product Details

The MAX14588 evaluation kit (EV kit) is a fully assembled and tested circuit board that demonstrates the MAX14588 adjustable overcurrent and overvoltage protector. The EV kit features a transient voltage suppressor (TVS) diode on the input and a Schottky diode on the output. Input power to the EV kit uses a 4.5V to 36V input supply.

The EV kit circuit can be configured to demonstrate the device’s different current-limit types, adjustable overvoltage, undervoltage, and current-limit threshold.
