and Power Path Charger for Small Li+ General Description The MAX77650/MAX77651 provide highly-integrated battery charging and power supply solutions for low-power
wearable applications where size and efficiency are
critical. Both devices feature a SIMO buck-boost regulator
that provides three independently programmable power
rails from a single inductor to minimize total solution
size. A 150mA LDO provides ripple rejection for audio
and other noise-sensitive applications. A highly configurable linear charger supports a wide range of Li+ battery
capacities and includes battery temperature monitoring
for additional safety (JEITA).
The devices include other features such as current sinks
for driving LED indicators and an analog multiplexer that
switches several internal voltage and current signals to an
external node for monitoring with an external ADC. A bidirectional I2C interface allows for configuring and checking the status of the devices. An internal on/off controller
provides a controlled startup sequence for the regulators
and provides supervisory functionality when the devices
are on. Numerous factory programmable options allow
the device to be tailored for many applications, enabling
faster time to market. Simplified Application Circuit
