MCP7381X LI-ION BATTERY CHARGER
EVALUATION BOARD USER ’S GUIDE
Chapter 1. Product Overview
1.1
INTRODUCTION
The MCP7381X Li-Ion Battery Charger Evaluation Board demonstrates the features
and abilities for Microchip’s MCP7381X Li-Ion Battery Charger Evaluation Board Sim-
ple, Miniature Single-Cell, Fully Integrated Li-Ion / Li-Polymer Charge Management
Controllers. The MCP73811/2 are standalone highly integrated linear Li-Ion battery
chargers that employ a constant current/constant voltage (CCCV) charge algorithm for
cost sensitive and space limited applications.
The MCP7381X Li-Ion Battery Charger Evaluation Board has two independent circuits
that are available to evaluate an USB port powered Li-Ion / Li-Polymer battery charger
and an ac-dc wall adapter powered Li-Ion / Li-Polymer battery charger. For an ac-dc
wall adapter powered battery charger, an external resistor (R PROG ) sets the magnitude
of the charge current up to 500 mA. When the USB port provides power to the battery
charger, the MCP73811 specifically adheres to the current limits governed by the USB
specification. The PROG pin selects two preset charge current rates of typical 85 mA
(Low) or 450 mA (High) and does not exceed 100 mA (Low) or 500 mA (High)
maximum charge current. As for USB regulation, a device may draw either low-power
at one unit load or high-power at 5 unit loads. A unit load is defined to be 100 mA. The
drawn current per unit load is an absolute maximum value, not an average over time.
