EV2720-RH-00A

1-Cell, 2.5A NVDC Buck Charger Evaluation Board with Serial Interface Control

Datasheet

Description

The EV2720-RH-00A is an evaluation board designed to demonstrate the capabilities of the MP2720, a highly-integrated, 2.5A, 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 (BC1.2) and non-standard adapter 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 MP2720 supports a fully customizable JEITA profile with configurable temperature windows and actions.

The EV2720-RH-00A supports an operating voltage up to 6.3V. It also 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.
