INTRODUCTION
The MCP7381X Low-Cost Li-Ion Battery Charger Evaluation Board demonstrates
Microchip's Simple, Miniature Single-Cell, Fully Integrated Li-Ion / Li-Polymer Charge
Management Controllers, MCP73811 and MCP73812. The MCP73811 is powered
from USB port to charge Li-Ion / Li-Polymer batteries. The charge current is logic
selectable between High (500 mA) and Low (100 mA). The MCP73812 is designed to
charge Li-Ion / Li-Polymer batteries with programmable charging current up to 500 mA
by a single resistor from a regulated 5V ac-dc wall adapter.
The MCP73811/2 require only minimum components to implement a completed circuit
of Li-Ion / Li-Polymer battery charge management in any systems. The development of
MCP73811/2 meets the challenges of today’s cost-sensitive and space-limited applica-
tions.
The MCP7381X Low-Cost Li-Ion Battery Charger Evaluation Board comes with a
pre-installed 5-Lead SOT-23 MCP73811 and a pre-installed 5-Lead SOT-23
MCP73812.
Typical applications for MCP73811/2 are Rechargeable Toys, Low-Cost Lithium-Ion /
Lithium-Polymer Battery Chargers, Electronic Cigarettes, Rechargeable Portable
Electronic Devices, Bluetooth Headsets or USB Chargers.
FEATURES
The MCP7381X Low-Cost Li-Ion Battery Charger Evaluation Board has the following
features:
? Color coded test points ensuring the proper connections: Red for V DD and V BAT+ ;
Black for GND & V BAT- ;White for CE (Chip Enable).
? 2-position Dip Switch for charge current selections between USB_Low and
USB_High.
? Chip Enable (CE) Pin to disable the system when drive Low.
? Evaluating different charge current rates by changing R PROG (Programming
