SD5075 from Hangzhou SDIC Microelectronics, in a SOP-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 | Two-wire serial data line, I2C/SMBus compatible, which must be pulled up externally, and holding it low for more than 200 ms resets the two-wire interface to idle (open-drain) state (Trst 200 ms typical). |
| 2 | SCL | input | Two-wire serial clock line, I2C/SMBus compatible, which requires an external pull-up resistor. |
| 3 | ALARM | output | Open-drain over-temperature alarm output, also usable as SMBus Alert when configuration bit7 is set, with sink current of at least 4 mA at VOL=0.3V and leakage of at most 1 uA at VOH=VDD. |
| 4 | GND | power_in | Ground reference pin for the device. |
| 5 | A2 | input | Address select input that sets bit A2 of the 7-bit slave address (1001 A2 A1 A0, giving 48H to 4FH). |
| 6 | A1 | input | Address select input that sets bit A1 of the 7-bit slave address (1001 A2 A1 A0, giving 48H to 4FH). |
| 7 | A0 | input | Address select input that sets bit A0 of the 7-bit slave address (1001 A2 A1 A0, giving 48H to 4FH). |
| 8 | VDD | power_in | Supply pin with a working range of 2.7 V to 5.5 V and an absolute maximum of 7.0 V. |
