MT3303AT-EN
Magn Tek · Hall Switches · SOT-23
MT3303AT-EN from Magn Tek, in a SOT-23. 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 | VS | power_in | Supply voltage pin with an operating range of 2.8 V to 24 V and an absolute maximum of 27 V, referenced to GND. |
| 2 | OUT | output | Open-drain output, with a maximum output voltage of 27 V, a continuous output current limit of 50 mA, and a saturation voltage of 0.4 V max at 20 mA when B > BOP. |
| 3 | GND | power_in | Ground reference pin; all absolute maximum voltages are referenced to this pin. |
