4-Channel Current Limited Load Switch

General Description

Features

The AAT4644 is a four-channel resettable fuse. It

utilizes independent current-limited and thermally

protected P-channel MOSFETs to protect against

short circuits. Each switch's current limit is factory

programmed at 1A. Additional protection is provid-

ed with undervoltage lockout; the switches are

turned off when the input voltage drops below a

preset level. The quiescent supply current is typi-

cally 20µA. The AAT4644 is a flexible solution,

allowing system designers to gang outputs togeth-

er for lower R_DS(ON)and higher current limit.

•
