AAT3526/7/8
MicroPower Supervisory Circuit with Manual Reset
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
VCC 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
VCC. 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.
