TPSI3050DWZR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | EN | input | High-level active driver enable input; 0V to 5.5V in three-wire mode or 0V to 48V in two-wire mode; 65V/ms minimum slew rate recommended |
| 2 | PXFR | input | Power transfer control resistor connection to VSSP selecting one of seven occupancy settings (7.32kΩ at 13.3% to 20kΩ at 93.3%) to regulate secondary-side power delivery |
| 3 | VDDP | power_in | Primary-side power supply input; 3.0V to 5.5V in three-wire mode or 6.5V to 48V in two-wire mode; requires bypass capacitor 220nF (two-wire) or 0.22µF to 20µF (three-wire) |
| 4 | VSSP | power_in | Primary-side ground reference for VDDP, EN, and PXFR inputs; provides common return path with minimum 8.5mm creepage and clearance to secondary side |
| 5 | VSSS | power_in | Isolated secondary-side ground reference with 120µm minimum internal isolation gap; independent from primary VSSP by isolation barrier |
| 6 | VDDM | power_out | Internally generated mid-voltage auxiliary rail nominally 5V (4.6V to 5.5V under load) serving as charge divider between VDDH and VSSS; requires 0.003µF to 40µF capacitor to VSSS |
| 7 | VDDH | power_out | Internally generated isolated high-voltage rail nominally 10V (9.4V to 11V nominal, 8.3V to 9.0V rising threshold, 6.3V to 6.9V falling threshold) supplying floating gate drive power with 1.5A source and 3.0A sink current capability |
| 8 | VDRV | output | Isolated gate driver output from secondary side; 9.4V to 11V when driven high (1.5A source), 0V to 0.1V when driven low (3.0A sink); compatible with gate charges of 10nC to 100nC |
