MCP9800A0T-M 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 | VDD | power_in | Power supply input; the operating voltage specified in the DC electrical specification table is applied to this pin. |
| 2 | GND | power_in | System ground pin. |
| 3 | ALERT | output | Open-drain temperature alert output that signals when the ambient temperature goes beyond the user-programmed temperature limit. |
| 4 | SCLK | input | Serial clock input; all communication and timing is relative to this pin, and the clock is generated by the host controller on the bus. |
| 5 | SDA | bidirectional | Bidirectional serial data pin used to transmit data to and from the host controller, which requires a pull-up resistor to output data. |
