Product details

The STEF512PUR from STMicroelectronics is a power management IC in the Analog & Data Acquisition category. It is supplied in a 10-WFQFN package with a 10-QFN (2x3) supplier device package, surface-mount mounting.

Package and board-fit considerations

The 10-WFQFN package (2x3 mm body) is a fine-pitch, thermally enhanced QFN. The exposed pad on the underside must be soldered to a thermal land on the PCB to achieve the rated thermal performance. The 0.50 mm pitch requires careful solder-paste stencil design to avoid bridging between adjacent pads.

Frequently asked questions

What is the closest functional second-source for STEF512PUR?

The LM334DT is a current-source device from a different functional family (current source vs power management IC) and is not a direct functional replacement. The STEF033APUR and STEF033AJR are electronic fuses with a 3.1 V input and 3.6 A output, but they operate in a different voltage and current class than the STEF512PUR.

What compliance documentation does STMicroelectronics provide for STEF512PUR?

The part is ROHS3 compliant.
