EV2731-QC-00A

Wide-Input, 4.5A, I2C-Controlled SW Charger w/ NVDC Power Path and USB OTG Eval Board

Description

The EV2731-QC-00A is an evaluation board for designed to demonstrate the capabilities of the MP2731. The MP2731 is a wide-input, 4.5A, highly integrated switch-mode battery charger IC for single-cell Li-ion or Li-polymer batteries. This device supports NVDC architecture with power path management suitable for portable applications including tablets, mobile internet devices, and smartphones.

Its low-impedance power path optimizes efficiency, reduces battery charging time, and extends battery life. The I2C serial interface with charging and system settings allows the device to be flexibly controlled.

The EV2731-QC-00A supports up to 16V input sources, including standard USB host ports and high-voltage wall adapters with fast-charge capability. The EV2731-QC-00A supports USB On-the-Go (OTG) operation by supplying 5V with 3.0A.
