MCP9808-E

Microchip Tech · Temperature Sensors · MSOP-8

MCP9808-E from Microchip Tech, in a MSOP-8. 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 SDA bidirectional Serial data line for the 2-wire SMBus/I2C interface; it requires a pull-up resistor, has VOL max 0.4 V at IOL 3 mA, and a minimum IOL of 6 mA at VOL 0.6 V.
2 SCL input Serial clock input for the 2-wire interface, with all communication timed from this pin; its input levels are VIH min 0.7 VDD and VIL max 0.3 VDD, and it is clocked by the host controller.
3 Alert output Open-drain temperature alarm output that asserts when ambient temperature exceeds the user-programmed limits; it requires an external pull-up resistor, with VOL max 0.4 V at IOL 3 mA.
4 GND power_in System ground pin for the device.
5 A2 input Device address input, which must be tied to VDD or GND to set address bit A2 (A6-A0 address code per Table 3-2).
6 A1 input Device address input, which must be tied to VDD or GND to set address bit A1 (A6-A0 address code per Table 3-2).
7 A0 input Device address input, which must be tied to VDD or GND to set address bit A0 (A6-A0 address code per Table 3-2).
8 VDD power_in Supply pin; the operating voltage range is 2.7 V to 5.5 V per the DC characteristics table.

CAD (KiCad official)

  • Symbol: MCP9808-E
  • Footprint: Package_SO:MSOP-8_3x3mm_P0.65mm
  • 3D model: MSOP-8 (KiCad packages3D, STEP)
  • 3D model files: mcp9808-e-etched.step / mcp9808-e-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mcp9808-e.step / mcp9808-e.glb are the bare package body.
