GR61CN1902MR

GR · Supervisor And Reset ICs · SOT-23-3

GR61CN1902MR from GR, in a SOT-23-3. 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 VOUT output Chip output pin, available as N-channel open-drain or CMOS output, with the output voltage limited to VSS-0.3 V to VIN+0.3 V by the absolute maximum ratings.
2 VSS power_in Chip ground pin.
3 VIN power_in Start-up input pin that also serves as the supply (VDD = VIN); absolute maximum input voltage is 15 V and operating voltage is 1.5 V to 12 V.

CAD (KiCad official)

  • Symbol: GR61CN1902MR
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: gr61cn1902mr-etched.step / gr61cn1902mr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); gr61cn1902mr.step / gr61cn1902mr.glb are the bare package body.
