MAX77651 - Ultra-Low Power PMIC

This page provides the datasheet information for the MAX77651, a member of the MAX77650 Ultra-Low Power PMIC family.

Description

The MAX77650/MAX77651 provide highly-integrated battery charging and power supply solutions for low-power wearable applications where size and efficiency are critical.

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 tai.

MAX77650/MAX77651 EVALUATION KIT AVAILABLE Ultra-Low Power PMIC with 3-Output SIMO 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).
