MCP1630V参考设计主要为电源管理，电池充电器的设计提供参考。The MCP1630V Bi-directional 4 Cell Li-Ion Charger Reference Design demonstrates the use of a bidirectional buck-boost converter used to charge multiple series cell Li-Ion batteries with the presence of an input source (boost) and provide a regulated output voltage when the input source is removed (buck). The board also serves as a platform to evaluate the MCP1630V device.Features:
Four Cell Li-Ion Battery Charger operates stand-alone. (Additional firmware added allows the charger to communicate with smart battery packs)
Charges four cell Li-Ion battery pack from 6.5V to 7.0V Input (complete precondition, constant current and constant voltage charge algorithm in firmware)
Regulates input dc bus voltage, (steps battery pack voltage down), to 6.0V when input source is removed (providing uninterrupted power source for system)
ON/OFF button used to enable and disable system, low IQ drain on the battery when disabled (< 10 ?A)
Output over-voltage protection in the event of open battery connections
High efficiency over entire operating input voltage range (94% typical)
PIC16F88 is used to generate ref Voltage and Oscillator signal at 500 kHz frequency at maximum duty cycle
Proprietary features can be added by modifying the firmware contained in the PIC16F88
