General Description
The AAT3526/7/8 PowerManager products are
members of AATI's Total Power Management IC
(TPMIC) product family. These microprocessor
reset circuits are ideal for monitoring voltage sup-
plies in portable systems, where extended battery
life is critical. They provide a low cost, reliable solu-
tion by eliminating external components. The
AAT3526/7/8 products operate 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 minimum of 150ms after
V
CC
has risen back above the fixed threshold. They
are guaranteed to operate down to 1.2V and
designed to ignore fast line transients appearing on
V
CC
. The AAT3526/7/8 series is available with three
output stage versions: AAT3526 push-pull active
low output, AAT3527 push-pull active high output
and AAT3528 open drain active low output. The
quiescent supply current is extremely low, typically
1μA, making this device ideal for portable battery
operated equipment.
The AAT3526/7/8 are available in a 4 pin SOT143
package and are specified over -40° to 85°C oper-
ating temperature range.
Features
1.2V to 5.5V Input voltage range
Operation down to 1.2V
Extremely low quiescent current: less than 2μA
High accuracy detection threshold: ±1.5%
Monitor Power Supply Voltages
Fixed thresholds from 2.2V to 4.6V
Minimum 150ms reset pulse width with fast
delay time <20μs
Debounced Manual Reset Input
Available output configurations:
Open-drain output
CMOS active high output
CMOS active low output
Temp range -40 to 85°C
4 pin SOT143 package
