A1230LLTR-T from Allegro MicroSystems, LLC, in a SOIC-8. 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 | Connects power supply to the on-chip voltage regulator; operating range 3.3 to 18 V (absolute maximum 26.5 V, reverse battery -16 V). |
| 2 | OUTPUTA | output | Open-drain output from Hall element E1 via the first Schmitt circuit, requires a pull-up resistor, sinks up to 20 mA with 160 mV typical low-level voltage. |
| 3 | OUTPUTB | output | Open-drain output from Hall element E2 via the second Schmitt circuit, requires a pull-up resistor, sinks up to 20 mA with 160 mV typical low-level voltage. |
| 4 | GND | power_in | Terminal for ground connection. |
| 5 | NC | unconnected | No connection. |
| 6 | NC | unconnected | No connection. |
| 7 | NC | unconnected | No connection. |
| 8 | NC | unconnected | No connection. |
