Product details

High-side switch for USB and general-purpose power rails

The switch is enabled by a logic-level On/Off input (non-inverting) and requires no separate Vcc supply — the gate drive is derived from the load voltage.

Protection set and fault flag

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 point to the downstream load — useful for USB ports where the limit must comply with 0.5 A (USB 2.0) or 1.5 A (USB 3.0) per port. A status flag output signals over-current or over-temperature events, which a host controller can read to manage the fault.

Package and thermal: 6-WSON with exposed pad

The TPS2553DRVR is supplied in a 6-pin WDFN with exposed pad (6-WSON, 2 mm x 2 mm body). The small footprint makes it suitable for space-constrained designs like USB hubs, portable docks, and battery-powered equipment.

Frequently asked questions

What is the function of TPS2553DRVR?

The TPS2553DRVR is a high-side power distribution switch. It connects a load voltage (2.5 V to 6.5 V) to the output when enabled, with a typical on-resistance of 100 mOhm and a maximum continuous output current of 1.5 A. It includes adjustable current limiting, over-temperature protection, and a status flag.

Is TPS2553DRVR a high-side switch?

Yes, the TPS2553DRVR is a high-side switch — it connects the load to the positive supply rail. The output configuration is high side with an N-channel MOSFET, and the input-to-output ratio is 1:1.
