Product details

The TPS2559DRCR: This Rds(on) sets the voltage drop and self-heating at full load: at 5.5 A the conduction loss is under 400 mW, which the 10-VFDFN exposed-pad package (3x3 mm VSON) must sink through the thermal pad and board vias.

Adjustable current limiting and fault protection — USB and general-purpose rail fit

Fault protection includes adjustable current limiting, over-temperature shutdown, and undervoltage lockout (UVLO). The current limit is set with an external resistor, allowing the designer to tailor the trip threshold below the 5.5 A maximum for USB ports, peripheral rails, or point-of-load switches. The status flag output signals overcurrent or thermal fault conditions to the system controller.

Frequently asked questions

Is TPS2559DRCR compatible with 5V logic for the enable input?

The switch uses a non-inverting On/Off interface with an input type listed as non-inverting. The enable threshold is compatible with 5V logic levels when the load supply is within the 2.5 V to 6.5 V range, as the enable pin is referenced to the input voltage.

Is TPS2559DRCR compatible with USB power management?

Yes. The adjustable current limiting, slew-rate-controlled turn-on, and status flag output align with USB port power-switch requirements. The 5.5 A maximum output covers USB 2.0 (500 mA), USB 3.0 (900 mA), and USB-C power delivery applications within the 2.5 V to 6.5 V load range.
