Microchip MCP1632 | Demoboard DS50002321A

Description

The MCP1632 Single-Cell Li-Ion Battery Charger Demo Board is a step-up/step-down, switch-mode, DC/DC converter used for battery charging applications. The demo board provides a 4.2V constant voltage source. Other output voltages can be obtained with minor modifications to the board’s Bill of Materials (BOM).The MCP1632 Single-Cell Li-Ion Battery Charger Demo Board is an intelligent battery charging system for a single-cell Lithium-Ion battery. MCP1632 Single-Cell Li-Ion Battery Charger Demo Board utilizes Microchip's MCP1632 high-speed Pulse-Width Modulator (PWM). The 8-pin MCP1632 device contains all the analog components necessary for a peak current mode control loop including an error amplifier, PWM comparator and a high-current driver output pin.An 8-pin PIC12F1822 microcontroller is used to implement the charging algorithm. In addition, the PIC12F1822 firmware supervises the battery voltage and current.
