Product details

2.5 A per channel, 44 mOhm — dual high-side switch for USB and general-purpose power distribution

It integrates adjustable current limiting, over-temperature protection, and undervoltage lockout (UVLO) in a single 10-VSON (3x3 mm) package. The part is designed for USB ports, set-top boxes, and other 2.5 V to 6.5 V power-distribution applications where each output needs independent on/off control via a non-inverting logic input.

Adjustable current limit — set the trip point per channel with one resistor

The fault protection set includes adjustable current limiting (one external resistor per channel), over-temperature shutdown, and UVLO. The slew-rate-controlled turn-on reduces inrush current, and the status flag output reports over-current or thermal fault conditions. Because the supply voltage (Vcc/Vdd) is not required — the switch is self-powered from the load voltage rail — the part simplifies layout by eliminating a separate bias rail.

Frequently asked questions

What is the maximum output current of TPS2561DRCT?

The TPS2561DRCT is rated for 2.5 A maximum per channel. The actual current limit is adjustable with an external resistor, so the designer sets the trip point below 2.5 A to match the load and PCB thermal capability.

Can TPS2561DRCT replace TPS2561DRCR?

The TPS2561DRCT and TPS2561DRCR share the same base product number TPS2561 and the same 10-VSON (3x3 mm) package. The difference is the shipping medium: the DRCT suffix indicates Tape & Reel or Cut Tape, while the DRCR suffix typically indicates a different reel quantity or tube. Electrically they are identical — confirm the reel quantity and tape width against your pick-and-place setup before substituting.
