General Description
The AAT4684 OVPSwitch™ is a member of Skyworks'
Application Specific Power MOSFET™ (ASPM™) product
family. It is a P-channel MOSFET power switch with pre-
cise 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 damage to the output load
circuits. The AAT4684 is available with an internally pro-
grammed over-voltage trip point or as an adjustable
version programmed by two external resistors.
The AAT4684 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 AAT4684 is offered in a small Pb-free, 12-pin
TSOPJW package and is specified for operation over the
-40°C to +85°C ambient temperature range.
