BCR 401W H6327
Infineon Technologies · LED Drivers · SOT-343
BCR 401W H6327 from Infineon Technologies, in a SOT-343. 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 | GND | power_in | Ground pin of the LED driver; dimming is possible by using an external digital transistor at this pin. |
| 2 | IOUT | output | LED current output, preset to 10 mA and adjustable up to 60 mA with Rext, with maximum output voltage of 18 V. |
| 3 | VS | power_in | Supply voltage pin, up to 18 V maximum with a 1.2 V typical minimum voltage overhead. |
| 4 | Rext | passive | Optional external resistor connection in parallel with the internal 79 Ω resistor to raise output current from 10 mA up to 60 mA. |
