CHI932TB from COSEMITECH, in a TO-92S. 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 | VDD | power_in | Supply voltage pin, operating range 2.5 V to 22 V (absolute maximum 24 V, reverse voltage protected to -22 V). |
| 2 | GND | power_in | Ground pin. |
| 3 | OUT | output | Open-drain output pin that sinks up to 25 mA (absolute maximum), goes low when the field exceeds BOP and releases below BRP, with output voltage rated -0.3 V to 24 V. |
