Microchip Tech · Digital Potentiometers · TSSOP-14
MCP45HV51-104E 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; a decoupling capacitor to DGND is recommended. |
| 2 | SCL | input | I2C serial clock input (Schmitt trigger), connected to the host controller's SCL; the device is an I2C client so this is input-only. |
| 3 | A1 | input | I2C address bit 1 input (Schmitt trigger); with A0 allows up to four devices on one I2C bus. |
| 4 | SDA | bidirectional | I2C serial data input/output (Schmitt trigger) with an open-drain N-channel driver, used to read and write the Wiper and TCON registers. |
| 5 | A0 | input | I2C address bit 0 input (Schmitt trigger), latched at POR/BOR; with A1 completes the device address. |
| 6 | WLAT | input | Wiper latch enable input: 0 transfers the received I2C shift register value to the Wiper register, 1 holds the received value in the shift register buffer. |
| 7 | NC | unconnected | Not internally connected to the die; to reduce noise coupling, connect to DGND or VL. |
| 8 | SHDN | input | Shutdown input (Schmitt trigger) that forces the resistor network terminals into the hardware shutdown state. |
| 9 | DGND | power_in | Digital ground reference for the device. |
| 10 | V- | power_in | Analog negative potential supply; must be lower than or equal to the DGND potential. |
| 11 | P0B | passive | Potentiometer 0 Terminal B (zero-scale wiper end, code 0x00), non-polarized, supports positive and negative current, voltage must be between V+ and V-. |
| 12 | P0W | passive | Potentiometer 0 wiper terminal, non-polarized, supports positive and negative current, voltage must be between V+ and V-. |
| 13 | P0A | passive | Potentiometer 0 Terminal A (full-scale wiper end, 0xFF for 8-bit), non-polarized, supports positive and negative current, voltage must be between V+ and V-. |
| 14 | V+ | power_in | Analog positive supply voltage; must be at a higher potential than the V- pin (maximum 36V analog range). |
