The MAX14571EUD+ is an adjustable overvoltage and overcurrent protector with high accuracy in 14 pin TSSOP package. The adjustable overvoltage and overcurrent-protection devices are ideal to protect systems against positive and negative input voltage faults up to ±40V and feature low 100Mohm (typ) RON FETs. The overvoltage-protector (OVP) feature protects voltages between 6V and 36V while the undervoltage-protector (UVP) feature protects voltages 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 19.2V (typ). The device also features programmable current-limit protection up to 4.2A. Once current reaches the threshold, the MAX14571 turns off after the 20.7ms (typ) blanking time and stays off during the retry period when set to autoretry mode.
Supply voltage range is 4.5V to 3.6V
