GP8212S-TC50-EW from Guestgood, in a ESOP-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 | SCLK | input | I2C protocol clock signal input for the GP8212S; the datasheet gives an I2C clock frequency of 400 kHz. |
| 2 | SDA | bidirectional | I2C protocol data line carrying the 15-bit DATA word and configuration bytes; the datasheet specifies an I2C high-level input of 2.7 V to 5.5 V. |
| 3 | NC | unconnected | No internal connection; leave floating. |
| 4 | V5V | power_out | Internal LDO 5 V output that must be decoupled with an external 1 uF capacitor. |
| 5 | GND | power_in | Ground reference for the device. |
| 6 | VCC | power_in | Supply input; the datasheet gives a supply range of 9 V to 36 V (typical 24 V). |
| 7 | FB | input | Voltage feedback input that samples the sense resistor for closed-loop current control; the typical choice is Rs = 100 Ω, giving IOUT = 2.5 V/Rs × DATA/0x7FFF. |
| 8 | IOUT | output | Analog current output (4-20 mA / 0-20 mA), with a load resistance of 800 Ω listed at VCC = 24 V. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
