A1152LLHLX-T from Allegro MicroSystems, LLC, in a SOT-23W. 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 | Input power supply; operating range 3.0 to 24 V (absolute maximum 28 V forward, -18 V reverse). |
| 2 | NC | unconnected | No connection on the LH package and not internally connected to IC ground; highly recommended to tie to GND for maximum EMC and ESD robustness. |
| 3 | GND | power_in | Ground terminal. |
