Description

span id="lblDescription">

The AAT4686 OVPSwitch™ is a member of AnalogicTech 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 < 1?a of current.

The AAT4686 is offered in a small Pb free, 8-pin SC70JW package, and is specified for operation over the -40C to +85C ambient temperature range.
