Product details

Why the boost converter matters for a USB switch

The TPS2501DRCT integrates a boost converter to generate a gate-drive voltage above the input rail for its N-channel pass FETs. Without that internal boost, a standard N-channel switch would need an external charge pump or a higher supply rail to achieve the same on-resistance.

Two outputs, one small footprint

Two independent outputs, each rated for 1.4 A continuous, share the 10-VSON (3x3 mm) exposed-pad package. The 1:2 input-to-output ratio means a single upstream rail feeds both channels. The output configuration can be high-side or low-side, which gives flexibility for power-rail sequencing or load-switching on either the Vbus or ground side of a USB port.

Fault protection that covers the common failure modes

Adjustable current limiting lets you set the trip threshold per design, not just a fixed hard limit. The status flag output reports fault conditions back to the system controller.

Frequently asked questions

Is TPS2501DRCT compatible with 3.3 V logic?

The control interface is logic-level compatible (input type is non-inverting, interface is Logic), and the supply voltage range covers 3.3 V rails. The status flag output is an open-drain signal that pulls low on fault — it requires a pull-up resistor to the host logic voltage.
