CHI932TB

COSEMITECH · Magnetic Sensors · TO-92S

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.
