Product Overview

WHAT IS THE MCP7381X LI-ION BATTERY CHARGER EVALUATION
BOARD?
The MCP7381X Li-Ion Battery Charger Evaluation Board demonstrates the use of the
MCP73811/2 Simple, Miniature Single-Cell, Fully Integrated Li-Ion / Li-Polymer
Charger Management Controllers.
The MCP7381X Li-Ion Battery Charger Evaluation Board is setup to evaluate low cost
single-cell Li-Ion / Li-Polymer battery chargers. This board utilizes Microchip's
MCP7381X Li-Ion Battery Charger Evaluation Board that efficiently charge Li-Ion /
Li-Polymer batteries with a preset + 1% voltage accuracy regulation at 4.2V. The
MCP7381X Li-Ion Battery Charger Evaluation Board comes with two pre-installed cir-
cuits: An ac-dc adapter powered Li-Ion /Li-Polymer battery charger and an USB port
powered Li-Ion / Li-Polymer battery charger.
The MCP73811 is available for the USB port powered circuit while the MCP73812 is
designed for the ac-dc wall adapter powered circuit. A SOT-23-5 MCP73811 is
pre-installed on the evaluation board with a mechanical dip switch which selects charge
current High (450 mA) or Low (85 mA) for the USB port powered battery charger
system. A SOT23-5 MCP73812 is pre-installed on the evaluation board with a pro-
gramming resistor R PROG which delivers 500 mA from the ac-dc wall adapter source.
When the Chip Enable (CE) pin is in “High” condition, that particular circuit is ready to
charge single-cell Li-Ion batteries.
Note:
The systems are designed in operation mode with CE pin High and can be
disabled when driving CE pin Low.
The two dashed silk screen areas on the evaluation board show the required circuit
size for the printed circuit board (PCB) layout and provide system / product designers
a visual aid prior design the system.
The MCP7381X Li-Ion Battery Charger Evaluation Board is designed to observe the
performance and features via multiple test points that are available on the circuits.
Users are able to discover the compact size of the layout in addition to the device itself.
The circuit can also be implemented into suitable applications without any additional
works.
