MAX14720/MAX14750
Power-Management Solution
General Description
The MAX14720/MAX14750 are compact power-management
solutions for space-constrained, battery-powered applications
where size and efficiency are critical. Both devices integrate
a power switch, a linear regulator, a buck regulator, and a
buck-boost regulator.
The MAX14720 is designed to be the primary power-
management device and is ideal for either non-rechargeable
battery (coin-cell, dual alkaline) applications or for
rechargeable solutions where the battery is removable
and charged separately. The device includes a button
monitor and sequencer.
The MAX14750 works well as a companion to a charger
or PMIC in rechargeable applications. It provides direct
pin control of each function and allows greater flexibility
for controlling sequencing.
The devices include two programmable micro-IQ, high-
efficiency switching converters: a buck-boost regulator
and a synchronous buck regulator. These regulators
feature a burst mode for increased efficiency during light-
load operation.
The low-dropout linear regulator has a programmable
output. It can also operate as a power switch that can
disconnect the quiescent load of system peripherals.
The devices also include a power switch with battery-
monitoring capability. The switch can isolate the battery
from all system loads to maximize battery life when not
operating. It is also used to isolate the battery-impedance
measurements. This switch can operate as a general-
purpose load switch as well.
The MAX14720 includes a programmable power controller
that allows the device to be configured either for use in
applications that require a true off state or for always-on
applications. This controller provides a delayed reset signal,
voltage sequencing, and customized button timing for on/off
control and recovery hard reset.
Both devices also include a multiplexer for monitoring the
power inputs and outputs of each function.
These devices are available in a 25-bump, 0.4mm pitch,
2.26mm x 2.14mm wafer-level package (WLP) and operate
over the -40°C to +85°C extended temperature range.

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.
