NCT175DMR2G-TUDI from Tudi, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SDA | bidirectional | Serial data line for the SMBus / I2C two-wire interface. Open-drain output, requires an external pull-up resistor to V+. |
| 2 | SCL | input | Serial clock input for the SMBus / I2C two-wire interface. Open-drain, requires an external pull-up resistor. |
| 3 | ALERT | output | Over-temperature alert / interrupt output. Open-drain output (polarity selectable via POL bit); requires an external pull-up resistor. Asserts in Comparator or Interrupt mode when T_HIGH / T_LOW limits are exceeded. |
| 4 | GND | power_in | Device ground / power supply return. |
| 5 | A2 | input | I2C slave address select bit 2. Tie to V+ or GND to set the corresponding bit of the 7-bit slave address (1001_A2A1A0). |
| 6 | A1 | input | I2C slave address select bit 1. Tie to V+ or GND to set the corresponding bit of the 7-bit slave address (1001_A2A1A0). |
| 7 | A0 | input | I2C slave address select bit 0. Tie to V+ or GND to set the corresponding bit of the 7-bit slave address (1001_A2A1A0). |
| 8 | V+ | power_in | Positive supply voltage input. Operating range 1.4 V to 5.5 V (absolute max 6 V). Bypass to GND with a 0.1 uF ceramic capacitor close to the pin. |
