General Description

The AAT3520 series of PowerManager products is

part of AnalogicTech's Total Power Management

IC™ (TPMIC™) product family.

processor reset circuits are ideal for monitoring volt-

age supplies in portable systems, where extended

battery life is critical. They provide a low-cost, reli-

able solution by eliminating the need for external

components.

monitoring the system power supply voltage. When

the input voltage drops below a fixed threshold, the

device asserts a reset signal for a fixed time period

after V

30ms and 150ms minimum periods are available.

The AAT3520 product series is guaranteed to oper-

ate down to 1.2V and is designed to ignore fast line

transients appearing on V

is available with three output stage versions:

AAT3520 push-pull active high output; AAT3522

push-pull active low output; and AAT3524 open

drain active low output. The quiescent supply cur-

rent is extremely low, typically 1µA, making it ideal

for portable battery-operated equipment.

The AAT3520/2/4 are available in a Pb-free, 3-pin

SOT23 package and are specified over the -40°C

to +85°C operating temperature range.
