MCP45HV51-103E from Microchip Tech, in a TSSOP-14. 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 | VL | power_in | Positive digital power supply input, relative to DGND, ranging from 1.8V to 5.5V, with a decoupling capacitor to DGND recommended. |
| 2 | SCL | input | I2C serial clock input, input-only for the I2C client device, with a Schmitt-trigger buffer. |
| 3 | A1 | input | I2C address bit 1 input, which together with A0 sets the device address so up to four devices can share one I2C bus. |
| 4 | SDA | bidirectional | I2C serial data pin, an open-drain N-channel driver that carries data in and out for the wiper and TCON registers. |
| 5 | A0 | input | I2C address bit 0 input, latched at POR/BOR, which together with A1 completes the device address. |
| 6 | WLAT | input | Wiper latch enable that holds off transfer of the received wiper value to the Wiper register while held high and allows the update when low. |
| 7 | NC | unconnected | Not internally connected to the die; to reduce noise coupling, connect to either DGND or VL. |
| 8 | SHDN | input | Shutdown input that forces the resistor network terminals into the hardware shutdown state. |
| 9 | DGND | power_in | Digital ground reference for the device, with VL and the digital logic referenced to it. |
| 10 | V- | power_in | Analog negative potential supply, which must be lower than or equal to the DGND pin potential. |
| 11 | P0B | passive | Potentiometer 0 Terminal B, the fixed connection to the zero-scale wiper value, with voltage that must be between V+ and V-. |
| 12 | P0W | passive | Potentiometer 0 wiper terminal, the adjustable terminal, with voltage that must be between V+ and V- and supporting both positive and negative current. |
| 13 | P0A | passive | Potentiometer 0 Terminal A, the fixed connection to the full-scale wiper value, with voltage that must be between V+ and V-. |
| 14 | V+ | power_in | Analog positive potential supply, which must have a higher potential than the V- pin. |
