Infineon Technologies · Gate Drivers · SOT-23-6
1EDN8550B from Infineon Technologies, in a SOT-23-6. 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 | IN- | input | Negative differential input, connected to controller ground via a resistor (typically 33 kΩ); the input voltage operating range is -7 V to 6 V, with an absolute maximum of -10 V to 10 V. |
| 2 | GND | power_in | Driver ground, which is the reference for the negative gate drive voltage in the "off" state. |
| 3 | IN+ | input | Positive differential input, connected to the controller PWM output via a resistor (typically 33 kΩ); the input voltage operating range is -7 V to 6 V, with an absolute maximum of -10 V to 10 V. |
| 4 | VDD | power_in | Positive supply voltage and positive gate drive voltage in the "on" state; the operating range is 4.5 V to 20 V (minimum set by UVLO), with an absolute maximum of 22 V. |
| 5 | OUT_SRC | output | Driver output source, a low-impedance pMOS switch to VDD rated 4 A typical sourcing current with Ron of 0.85 Ω. |
| 6 | OUT_SNK | output | Driver output sink, a low-impedance nMOS switch to GND rated 8 A typical sinking current with Ron of 0.35 Ω. |
