GH1495ALSY from GoChip Elec Tech Shanghai, in a SOT-89. 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 pin, specified for a 4.5 V to 10.5 V operating range. |
| 2 | Gnd | power_in | Ground reference pin; the datasheet labels its function only as '低' (low) and gives no further limit. |
| 3 | Vout | output | Ratiometric analog output proportional to supply voltage and magnetic field, with typical swing 0.2 V to (VCC-0.2) V and maximum swing 0.4 V to (VCC-0.4) V. |
