Analog Devices / Maxim Integrated MAX77650/MAX77651 Ultra-Low Power PMICs

Analog Devices MAX77650/MAX77651 Ultra-Low Power PMICs are an excellent solution for low-power wearable applications, with highly-integrated battery charging and efficiency. To minimize solution size, the PMICs feature a SIMO buck-boost regulator, that offers three independently programmable power rails from a single inductor. Ripple rejection for audio and other noise-sensitive applications is provided by a single 150mA LDO.

The Analog Devices MAX77650/MAX77651 has a linear charger that is highly configurable and supports a wide range of Li+ battery capacities. Battery temperature monitoring is included for additional safety (JEITA). A wide array of factory programmable options make the PMICs suitable for numerous applications.
