The MP2772 is a highly integrated switching battery charger that provides a complete solution for wearable and portable devices. The device provides an 8-bit successive approximation register (SAR) analog-to-digital converter (ADC) for battery and system monitoring, smart power-path management, narrow-voltage DC (NVDC) charging, push-button control, integrated load switches with an individual enable function, and an autonomous battery charging profile.
It integrates a battery charger, boost converter, and two embedded load switches into a single device. Only one inductor is required to charge a battery or boost the battery voltage to charge the device through load switches.
Main Features:
- High-Performance Buck Charger
- Boost Operation
- Safety Timers for Fast Charge, Pre-Charge, and Watchdog
