Low-Power Battery Backup
Circuits in Small μDFN Packages
General Description
The MAX16033–MAX16040 supervisory circuits reduce
the complexity and number of components required for
power-supply monitoring and battery control functions
in microprocessor (μP) systems. The devices signifi-
cantly improve system reliability and accuracy com-
pared to other ICs or discrete components. The
MAX16033–MAX16040 provide μP reset, backup-bat-
tery switchover, power-fail warning, watchdog, and
chip-enable gating features.
The MAX16033–MAX16040 operate from supply volt-
ages up to 5.5V. The factory-set reset threshold voltage
ranges from 2.32V to 4.63V. The devices feature a man-
ual-reset input (MAX16033/MAX16037), a watchdog
timer input (MAX16034/MAX16038), a battery-on output
(MAX16035/MAX16039), an auxiliary adjustable reset
input (MAX16036/MAX16040), and chip-enable gating
(MAX16033 –MAX16036). Each device includes a
power-fail comparator and offers an active-low push-
pull reset or an active-low open-drain reset.
The MAX16033 –MAX16040 are available in 2mm x
2mm, 8-pin or 10-pin μDFN packages and are fully
specified from -40°C to +85°C.
Features
o Low 1.2V Operating Supply Voltage
o Precision Monitoring of 5.0V, 3.3V, 3.0V, and 2.5V
Power-Supply Voltages
o Independent Power-Fail Comparator
o Debounced Manual-Reset Input
o Watchdog Timer, 1.6s Timeout
o Battery-On Output Indicator
o Auxiliary User-Adjustable RESETIN
o Low 13 μ A Quiescent Supply Current
o Two Available Output Structures:
Active-Low Push-Pull Reset
Active-Low Open-Drain Reset
o Active-Low Reset Valid Down to 1.2V
o Power-Supply Transient Immunity
o 140ms (min) Reset Timeout Period
o Small 2mm x 2mm, 8-Pin and 10-Pin μ DFN
