The AAT4687 OVPSwitch™ is a member of AnalogicTech’s Application Specific Power MOSFET™ (ASPM™) product family. It is a P-channel MOSFET power switch with pre-ci over-voltage protection control, designed to protect low-voltage systems against high-voltage faults up to +28V. If the input voltage exceeds the programmed over-voltage threshold, the P-channel MOSFET switch will be turned off to prevent the output load circuits from damage. The AAT4687 is available with an internally programmed over-voltage trip point or as an adjustable version programmed by two external resistors.
The AAT4687 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 AAT4687 also includes an enable pin (EN) to enable or disable the device and an OVP, OTP fault indicator (FLT).
The AAT4687 is offered in a small Pb-free, 10 pin SC70JW package, and is specified for operation over the -40°C to +85°C ambient temperature range.•Over-Voltage Protection up to 28V
