MAX14573EUD+, Special Function IC, Overvoltage & Overcurrent Protector, 4.5 V to 36 V in, TSSOP-14
The MAX14573EUD+ 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. The device limits the current continuously when set to continuous mode.
• Supply voltage range is 4.5V to 36V
