TPSI3050SDWZR

Texas Instruments · Gate Drivers · SOIC-8

TPSI3050SDWZR from Texas Instruments, 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 EN input Active high driver enable, rated 0 to 48 V in two-wire mode and 0 to 5.5 V in three-wire mode (with respect to VSSP).
2 PXFR input An external resistor from PXFR to VSSP selects one of seven power transfer levels, setting the converter duty cycle in three-wire mode or the EN current limit in two-wire mode; the power transfer control input is rated 0 to 5.5 V.
3 VDDP power_in Primary side supply, 3.0 to 5.5 V in three-wire mode (with respect to VSSP), with 0.22 to 20 µF decoupling to VSSP.
4 VSSP power_in Ground supply for the primary side, the reference for the primary-side voltages (EN, PXFR, VDDP).
5 VSSS power_in Ground supply for the secondary side, the reference for the secondary-side voltages (VDRV, VDDH, VDDM).
6 VDDM power_out Generated mid supply on the secondary side, absolute maximum 6 V with respect to VSSS, with 0.003 to 40 µF decoupling across VDDM and VSSS.
7 VDDH power_out Generated high supply on the secondary side, absolute maximum 12 V with respect to VSSS, with VDDH to VDDM limited to 6 V and 0.003 to 40 µF decoupling across VDDH and VDDM.
8 VDRV output Active high driver output for the external power switch, absolute maximum 12 V with respect to VSSS, providing a nominal 10 V gate drive with 1.5/3.0 A peak source and sink current.
