MAX77650/MAX77651

Ultra-Low Power PMIC with 3-Output SIMO

and Power Path Charger for Small Li+

General Description

Beneﬁts and Features

● Highly Integrated

The MAX77650/MAX77651 provide highly-integrated bat-

tery 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 configu-

rable linear charger supports a wide range of Li+ battery

capacities and includes battery temperature monitoring

for additional safety (JEITA).

• Smart Power Selector™ Li+/Li-Poly Charger

• 3 Output, Single-Inductor Multiple-Output (SIMO)

Buck-Boost Regulator

• 150mA LDO

• 3-Channel Current Sink Driver

• Analog MUX Output for Power Monitoring

● Low Power

• 0.3μA Shutdown Current

• 5.6μA Operating Current (3 SIMO Channels +

LDO)

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 bidi-

● Charger Optimized for Small Battery Size

• Programmable Fast-Charge Current from 7.5mA to

300mA

• Programmable Battery Regulation Voltage from

3.6V to 4.6V

rectional I C interface allows for configuring and check-

ing 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.

• Programmable Termination Current from 0.375mA

to 45mA

• JEITA Battery Temperature Monitors Adjust Charge
