SD5075

Hangzhou SDIC Microelectronics · Temperature Sensors · SOP-8

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.
