过压与过流保护器, 4.5 V至36 V输入, TSSOP-14

The 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.
