AAT4702 Over-Voltage Protection Switch

The AAT4702 OVPSwitch™ is a P-channel MOSFET power switch with precise over-voltage protection control, designed to protect low-voltage systems against high-voltage faults up to +28V. If the input voltage exceeds the fixed over-voltage threshold, the P-channel MOSFET switch will be turned off to prevent the output load circuits from damage. The AAT4702 is available with an internally programmed over-voltage trip point. The AAT4702 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 AAT4702 also includes an enable pin (EN) to enable or disable the device and an Over-volatege protection (OVP), Over-temperature protection (OTP) fault indicator (FLT). The AAT4702 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.
