GXCAS · Temperature Sensors · SOT-23-6
GX122 from GXCAS, in a SOT-23-6. 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 | ALERT | output | Open-drain alarm output that is active low by default (POL=0) and can be set active high via the POL bit; it requires an external pull-up resistor, with VOL of 0.4 V max at 4 mA sink and leakage of ±1 µA for 0 V ≤ VIN ≤ 6 V. |
| 2 | GND | power_in | Ground reference for the device. |
| 3 | VDD | power_in | Supply pin with an operating range of 2.7 V to 5.5 V, where a 0.1 µF bypass capacitor is recommended. |
| 4 | SO/I | bidirectional | Serial data output/input for the SPI interface, with VOL of 0.4 V max at 3 mA sink and VOH of (V+)-0.4 V min at 2 mA source, and it goes high impedance when CS is released. |
| 5 | /CS | input | Active-low SPI chip select; pulling it low starts a data transfer, and input logic levels are VIH of 0.7(V+) min and VIL of 0.3(V+) max. |
| 6 | SCK | input | SPI serial clock input with a minimum SCK period of 100 ns, and input logic levels of VIH 0.7(V+) min and VIL 0.3(V+) max. |
