CH481U00TB05501800

COSEMITECH · Hall Switches · TO-92S

CH481U00TB05501800 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; the on-board regulator allows operation from 2.8 V to 28 V, and the device withstands reverse battery down to -24 V.
2 GND power_in Ground pin; the device is protected if VCC and GND are reversed, up to -24 V.
3 OUT output Open-drain NMOS output that must be pulled up through an external resistor, with an output off voltage limit of -0.3 V to 30 V, a sink current limit of 25 mA absolute maximum, and short-circuit protection.
