Product details

1.5 A high-side switch with adjustable current limit

The TPS2552DRVT-1: The 100 mOhm typical on-resistance keeps voltage drop under 150 mV at full load, which matters for USB and 5 V rail distribution where the downstream device sees the switch's drop as a loss in input headroom.

Supply range and fault protection

Fault protection includes adjustable current limiting, over-temperature shutdown, and undervoltage lockout — the current limit is set with an external resistor, so the trip threshold can be dialled to match the load's inrush profile.

Orientation mark is on pin 1 corner; the package is symmetric enough that a misalignment on reflow will short the adjacent pins.

Frequently asked questions

Is TPS2552DRVT-1 suitable for USB power switch application?

Yes. The 1.5 A output exceeds the USB 2.0 500 mA and USB 3.0 900 mA per-port limits, and the adjustable current limit can be set below 1.5 A to match the host controller's overcurrent threshold. The slew-rate controlled turn-on prevents inrush from drooping the 5 V rail during hot-plug events.

What is the output current limit of TPS2552DRVT-1?

The maximum continuous output current is 1.5 A. The current limit is adjustable via an external resistor — the datasheet provides the resistor value vs. threshold table. The fault protection also includes over-temperature and UVLO.
