AAT4670

Dual-Input, Dual-Output Load Switch

™

SmartSwitch

General Description

Features

The AAT4670 SmartSwitch is a member of

AnalogicTech’s Application Specific Power MOS-

FET™ (ASPM™) product family. The AAT4670

consists of dual, independent, 1A current limited,

slew rate controlled P-channel MOSFET power

switches with a dedicated source and drain pin

assigned to each switch. The internal circuitry auto-

matically derives power from the higher of the two

input power source pins with a low operating quies-

cent current of 18µA. In shutdown mode, the supply

current decreases to less than 1µA. The switches

operate with inputs ranging from 2.2V to 5.5V, mak-

ing them ideal for 2.5V, 3V, and 5V systems. The

dual configuration permits integration of the load

switch function for systems with two different power

busses. Independent under-voltage lockout circuits

will shut down the corresponding switch if its input

voltage falls below the under-voltage lockout thresh-

old. If the die temperature reaches the thermal limit,

both switches thermal cycle off and on indefinitely

without damage until the thermal condition is

removed. An open drain FAULT output signals an

over-current or over-temperature condition for each

channel. Input logic levels are TTL compatible.
