MP2721

5A, 1-Cell, I²C-Controlled NVDC Buck Charger

Lockable Registers for Charging

Parameters

DESCRIPTION

The MP2721 is a highly integrated, 5A, switch-

mode battery management device for single-

cell Li-ion or Li-polymer batteries. The narrow-

voltage DC (NVDC) power management

structure provides a low-impedance power path

that optimizes charging efficiency, reduces

battery charging time, and extends battery life

during discharging.
