CH604ATB

COSEMITECH · Magnetic Sensors · TO-92S

CH604ATB 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 datasheet specifies a supply range of 3.0 V to 15 V (typical 5.0 V) and an absolute maximum supply voltage of 18 V.
2 GND power_in Ground pin.
3 OUT output Ratiometric linear output pin; the datasheet limits the output current to 5 mA absolute maximum and the output voltage to -0.3 V to 18 V.

CAD (KiCad official)

  • Symbol: CH604ATB
  • Footprint: Package_TO_SOT_THT:TO-92_Inline
  • 3D model: TO-92S (KiCad packages3D, STEP)
  • 3D model files: ch604atb-etched.step / ch604atb-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ch604atb.step / ch604atb.glb are the bare package body.
