µP Supervisory Circuits in
4-Bump (1mm x 1mm) Chip-Scale Package
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 excel-
lent 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 tran-
sients 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 pack-
age (UCSPTM).

Typical Operating Circuit
Note: All devices are specified over the -40NC to +85NC operat-
ing temperature range.
Insert the desired suffix numbers (from Table 1) into the blanks
“RS_ _D” to indicate the reset trip threshold. Insert the desired
suffix number (from Table 2) into the blank ”D_+” to indicate the
reset timeout. Minimum order quantity may apply.
