# MR6133SO

**Hallwee** · Hall Switches · SOT-23

MR6133SO from Hallwee, 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 | Vcc | power_in | Supply voltage input with a stated operating range of 1.65 V to 5.0 V and an absolute maximum supply voltage of 7 V. |
| 2 | OUT | output | Open-drain output on the MR6133 (push-pull is only on MR6131/MR6132); it goes low when the applied magnetic flux reaches BOP and high when it falls to BRP, with a maximum continuous output current of 20 mA and a maximum output voltage of 7 V, and requires an external pull-up (the datasheet example uses 100 kΩ). |
| 3 | GND | power_in | Ground reference pin; the datasheet specifies a reverse battery voltage limit of -0.4 V. |
