MAX16140B220KM+

P1-P3P4-P6P7-P9P10-P12
General Description
The MAX16140 is an ultra-low-current, single-channel
supervisory IC in a tiny, 4-bump, wafer-level package
(WLP). The MAX16140 monitors the V
CC
voltage from
1.7V to 4.85V in 50mV increments and asserts a reset
when V
CC
voltage falls below the reset threshold. The
reset output remains asserted for the reset timeout period
after the V
CC
voltage rises above the factory-set V
CC_TH
+ V
HYS
. See the Selector Guide for available reset timeout
options.
The MAX16140 includes a factory-programmable
manual reset input (MR) that can be configured to assert
a reset when it receives a rising-edge, falling-edge,
active-low, or active-high input signal. The MAX16140
features an open-drain reset output and is factory
programmable to either active-low or active-high reset
output configurations.
The MAX16140 is specified over the -40°C to +125°C
temperature range and are available in a tiny 0.78mm x
0.78mm x 0.5mm, 4-bump WLP.

Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
