Pinout
1. VDD (Pin 1): This is the input voltage supply pin, where you connect the positive terminal of the power source (typically between 3.75V to 6V).
2. VSS (Pin 2): This is the ground pin, serving as the common reference point for the input and output voltages.
3. STAT (Pin 3): This pin provides the status indicator for the charging process. It usually connects to an LED or microcontroller to indicate charging status.
4. VBAT (Pin 4): This pin is connected to the positive terminal of the battery and is where the charge current flows to the battery.
5. PROG (Pin 5): This pin sets the charge current by connecting a resistor between PROG and VSS.
The MCP73832 is designed for efficient and safe charging, offering features like thermal regulation, over-voltage protection, and battery status indication.
