Monolithic Power Systems MP2721 | Demoboard EV2721-RH-00A

Beschreibung

The EV2721-RH-00A is an evaluation board designed to demonstrate the capabilities of the MP2721, 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.
