The MAX17523 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) RON 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 MAX17523 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 MAX17523 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 MAX17523 also features reverse current and thermal shutdown protection.
The MAX17523 is available in a small, 16-pin (3mm x 3mm) TQFN package. The MAX17523 operates over the -40°C to +125°C extended temperature range.
