General Description
The AAT3520 series of PowerManager products is
part of AnalogicTech's Total Power Management
IC (TPMIC) product family. These micro-
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. The AAT3520 series operates by
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
CC
has risen back above the fixed threshold;
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
CC
. The AAT3520 series
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.
