Product details

Fault protection set — adjustable current limit, thermal shutdown, UVLO

The TPS2540RTER integrates adjustable current limiting, over-temperature protection, and under-voltage lockout (UVLO). The current limit is set with an external resistor. The status flag output (active-low, open-drain) signals over-current or thermal fault to the host controller.

Package and sourcing reality

The base product number is TPS2540, so any PCN or EOL notice will reference that family — worth monitoring if the BOM is locked for a multi-year production run. ROHS3 compliant.

Frequently asked questions

Can TPS2540RTER replace TPS2541?

The TPS2540 and TPS2541 are pin-compatible siblings in the same USB switch family. The TPS2541 adds a dedicated enable pin and may differ in fault-reporting logic. For a drop-in replacement, verify the control-logic requirements of your design — specifically whether the On/Off interface of the TPS2540 matches the enable scheme of the TPS2541.

Is TPS2540RTER RoHS compliant?

Yes, the TPS2540RTER is ROHS3 compliant.
