General Description
The AAT3520 Series of PowerManager products
is a member of AATI'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 external components.
The AAT3520 series operates by monitoring the
system power supply voltage. When the input volt-
age 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 operate
down to 1.2V and designed to ignore fast line tran-
sients 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 current is
extremely low, typically 1μA, making it ideal for
portable battery operated equipment.
The AAT3520/2/4 are available in a 3 pin SOT23
package and are specified over -40° to 85°C oper-
ating temperature range.
