Maxim’s MAX14588 is an adjustable over-voltage and over-current protection device for protecting systems against positive and negative input voltage faults up to ±40 V, and features low 190 mΩ RON integrated FETs.
The adjustable over-voltage range is between 6 V and 36 V, while the adjustable under-voltage range is between 4,5 V and 24 V. The over-voltage lockout (OVLO) and under-voltage lockout (UVLO) thresholds are set using optional external resistors. The factory preset internal OVLO threshold is 33 V and the preset internal UVLO threshold is 19 V.
The IC also features programmable current limit protection up to 1 A. It can be set for auto-retry, latch-off or continuous fault response when an over-current event occurs. Once current reaches the threshold, the MAX14588 turns off after a 21 ms blanking time and stays off during the retry period when set to auto-retry mode. The device latches off after the blanking time when set to latch-off mode, and it limits the current continuously when set to continuous mode.
The MAX14588 also features reverse current and thermal shutdown protection. It is available in a 16-pin, 3 x 3 mm TQFN package and operates over the -40°C to +125°C temperature range.
