Product details

The switch is self-contained — no external Vcc supply is needed because the gate drive is derived from the input voltage.

Fault protection set — no external sense resistor needed

Three built-in fault protections simplify the BOM: fixed current limiting (no external resistor), over-temperature shutdown, and under-voltage lockout (UVLO). The status flag output (open-drain, active low) asserts when the switch is in current limit or thermal shutdown, so a downstream GPIO or PLC input can log the fault without an ADC. The enable input is non-inverting — logic high turns the switch on.

Frequently asked questions

What is the TPS2051ADR used for?

It is a single-channel high-side power distribution switch, typically used for USB port power, general-purpose 5 V or 3.3 V rail switching, and fault-protected power distribution in industrial control and telecom equipment.

Is the TPS2051ADR RoHS compliant?

The part ships in a Tape & Reel package and is listed with a standard 8-SOIC body. Texas Instruments' standard RoHS compliance applies to this base product number — confirm the specific date-code compliance status at quote time.
