Product details

Dual 2.5 A channels with 44 mOhm on-resistance

This low Rds(on) keeps conduction loss under 275 mW at full load per channel, which matters when routing 5 A total through a 10-VSON package without a heatsink. Load voltage range spans 2.5 V to 6.5 V, covering 3.3 V and 5 V rails common in USB hubs, industrial I/O modules, and point-of-load distribution. The 1:2 input-to-output ratio means a single enable line gates both channels simultaneously.

Integrated fault protection and status flag

Built-in fault protection includes adjustable current limiting, over-temperature shutdown, and undervoltage lockout (UVLO). The status flag output signals over-current or thermal fault conditions to the host controller, allowing software-managed recovery or system power-down. Slew rate control on the output limits inrush current during hot-plug events, preventing upstream supply droop. The On/Off interface accepts a non-inverting logic-level enable, compatible with 1.8 V to 5 V logic without a level shifter.

The part does not require a Vcc/Vdd supply — it is self-powered from the load voltage.

Frequently asked questions

What is the closest pin-compatible alternative to TPS2561ADRCR?

The TPS2560 is a single-channel variant in the same family. For a dual-channel replacement, the TPS2561A (same base product number) shares the pinout and package. Confirm current limiting and fault response timing against your design before substituting.

Can TPS2561ADRCR replace TPS2560?

The TPS2561ADRCR is a dual-channel device; the TPS2560 is a single-channel part. They share the same package and pinout for the first channel, but the second output on the TPS2561ADRCR is not present on the TPS2560. A direct replacement is only possible if your design uses only one channel and the extra pin is left unconnected.
