MCP73832T-2DCI from Microchip Tech, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | STAT | output | Charge status output for an LED or a pull-up resistor to a host microcontroller; on the MCP73832 it is an open-drain output (tri-state on the MCP73831). |
| 2 | VSS | power_in | Battery management 0V reference; connect to the negative battery terminal and the input supply, and bypass VDD and VBAT to it. |
| 3 | VBAT | power_out | Battery charge control output connected to the positive battery terminal and the drain of the internal P-channel pass transistor; bypass to VSS with a minimum of 4.7 µF for loop stability when the battery is disconnected. |
| 4 | VDD | power_in | Battery management input supply, recommended at [VREG (typical) + 0.3V] to 6V and bypassed to VSS with a minimum of 4.7 µF. |
| 5 | PROG | input | Current regulation set and charge control enable: a resistor from PROG to VSS scales the preconditioning, fast charge and termination currents, while floating the pin or applying a logic-high signal disables the charger. |
