AAT4686 MOSFET Driver IC with Over-Voltage Protection

The AAT4686 OVPSwitch™ is a member of AnalogicTech’s Application Specific Power MOSFET™ (ASPM™) product family. It is a P-channel MOSFET driver IC with precise over-voltage protection control, designed to protect lowvoltage systems against high-voltage faults up to +28V. If the input voltage exceeds the programmed over-voltage threshold, the external P-channel MOSFET switch will be turned off to prevent damage to the output load circuits. The AAT4686 is available with an internally programmed over-voltage trip point or as an adjustable version programmed by a two external resistors. The AAT4686 also includes an under-voltage lockout (UVLO) protection circuit, which will put the device into sleep mode at low input voltages only consuming < 1μA of current. The AAT4686 is offered in a small Pb-free, 8-pin SC70JW package, and is specified for operation over the -40°C to +85°C ambient temperature range.
