EV2721-RH-00A

5A, Single-Cell, NVDC Buck Charger Evaluation Board with Serial Interface Control

Datasheet

Description

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.

USB Battery Charging Specification 1.2 (BC 1.2) and non-standard adaptor detection are supported by the input source type identification algorithm. The serial interface provides complete operating control, charging parameter configuration, and status/interrupt monitoring. The MP2721 supports a fully customizable JEITA profile with configurable temperature windows and actions.

The EV2721-RH-00A supports input sources up to 16V, including standard USB host ports and high-voltage wall adapters with fast charge capability. The EV2721-RH-00A supports boost mode and USB On-The-Go (OTG) operation by supplying a voltage between 5V and 5.35V at the IN pin, with up to 3A of current.
