MAX14745 Wearable Charge-Management Solution

Analog Devices MAX14745 Wearable Charge-Management Solution consists of a linear battery charger, a smart power selector, and many power-optimized peripherals. The MAX14745 was designed for low-power wearable applications such as fitness monitors and rechargeable IoT devices. Five regulated voltages are provided via the two ultra-low quiescent current buck regulators and three ultra-low quiescent current low-dropout (LDO) linear regulators. The regulators individually have an ultra-low quiescent current, enabling power consumption to a minimum and extending battery life. A smart power selector, as part of the Analog Devices MAX14745 Wearable Charge-Management Solution's battery charger, supports operation on a dead battery when connected to a power source.
