General Description
The MAX77654 provides highly-integrated battery charg-
ing and power supply solutions for low-power applications
where size and efficiency are critical. The IC features a
SIMO buck-boost regulator that provides three indepen-
dently programmable power rails from a single inductor to
minimize total solution size. Two 100mA LDOs provide rip-
ple rejection for audio and other noise-sensitive applica-
tions. The LDOs can also be configured as load switch-
es to manage power consumption by disconnecting exter-
nal blocks when not required. A highly-configurable linear
charger supports a wide range of Li+ battery capacities
and includes battery temperature monitoring for additional
safety (JEITA).
This device includes three GPIOs and an analog multi-
plexer that switches several internal voltage and current
signals to an external node for monitoring with an external
ADC. A bidirectional I
2
C serial interface allows for config-
uring and checking the status of the devices. An internal
on/off controller provides a controlled startup sequence for
the regulators and provides supervisory functionality while
they are on. Numerous factory programmable options al-
low the device to be tailored for many applications, en-
abling faster time to market.
Applications
Bluetooth Headphones, Hearables
Wireless Speakers
Fitness, Health, and Activity Monitors
Wearables
Safety and Security Monitors
Sensor Nodes
Portable Consumer Devices
