Low-Power µP Supervisory Circuits with
Battery-Backup Circuit and Chip-Enable Gating
General Description
The MAX16016/MAX16020/MAX16021 supervisory cir-
cuits monitor power supplies, provide battery-backup
control, and chip-enable (CE) gating to write protect
memory in microprocessor (µP)-based systems. These
low-power devices improve system reliability by providing
several supervisory functions in a small, single integrated
solution.
The MAX16016/MAX16020/MAX16021 perform four
basic system functions:
1) Provide a µP reset output during V
CC
supply power-
up, power-down, and brownout conditions.
2) Control V
CC
to battery-backup switching internally
to maintain data or low-power operation for memo-
ries, real-time clocks (RTCs), and other digital logic
when the main power is removed.
3) Provide memory write protection through internal
chip-enable gating during brownout.
4) Provide a combination of additional supervisory
functions listed in the
Features
section.
The MAX16016/MAX16020/MAX16021 operate from a
1.53V to 5.5V supply voltage and offer fixed reset
thresholds for monitoring 5V, 3.3V, 3V, 2.5V, and 1.8V
systems. Each device is available with either a push-
pull or open-drain reset output.
The MAX16016/MAX16020/MAX16021 are available in
small TDFN/TQFN packages and are fully specified for
an operating temperature range of -40°C to +85°C.
