General Description
The MAX16072/MAX16073/MAX16074 ultra-small, ultra-
low-power, microprocessor (μP) supervisory circuits feature
a precision band-gap reference, comparator, and
internally trimmed resistors that set the threshold voltage.
Designed to monitor the system supply voltage and assert
an output during power-up, power-down, and brownout
conditions, these devices provide excellent circuit reliability
and low cost by eliminating external components and
adjustments when monitoring nominal system voltage
from 1.8V to 3.6V.
The MAX16072 has a push-pull, active-low reset output,
the MAX16073 has a push-pull, active-high reset output,
and the MAX16074 has an open-drain active-low reset
output. The devices are designed to ignore fast transients
on VCC. The devices also include a manual reset input
(MR).
The MAX16072/MAX16073/MAX16074 are available in a
1mm x 1mm, space-saving, 4-bump, chip-scale package
(UCSP™).
