Monolithic Power Systems MP2721
The MP2721 is a highly integrated, 5A, switchmode battery management device for singlecell Li-ion or Li-polymer batteries. The narrowvoltage 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. The device’s input source type identification algorithm supports USB battery charging specification 1.2 (BC1.2) and non-standard adapter detection.| Part No. | MP2721 |
