WHAT IS THE MCP73213 OVP DUAL-CELL LI-ION BATTERY CHARGER
EVALUATION BOARD?
The MCP73213 OVP Dual-Cell Li-Ion Battery Charger Evaluation Board demonstrates
the features of Microchip’s MCP73213 “
Dual-Cell Li-Ion / Li-Polymer Battery Charge
Management Controller with Input Overvoltage Protection
”.
The MCP73213 OVP Dual-Cell Li-Ion Battery Charger Evaluation Board is designed
with two charging currents. The default value is 500 mA and when PROG via is tied to
ground, the two parallel resistors output 1000 mA charging current to a Li-Ion battery.
One blue LED status output allows the user to learn if the MCP73213 is in charging
state or not.
The MCP73213 OVP Dual-Cell Li-Ion Battery Charger Evaluation Board comes with an
installed MCP73213 device in the 3 mm x 3 mm DFN package. The factory preset
battery regulation voltage is 8.40V with 10% precondition current, 10% termination
current set point, automatic recharge and 6.5V OVP threshold voltage.
The MCP73213 OVP Dual-Cell Li-Ion Battery Charger Evaluation Board is designed to
observe the performance and features on the circuits via multiple test points. Circuits
can also be implemented into suitable applications without additional work.
