Product details

High-side switch with adjustable current limit

Its N-channel MOSFET delivers a typical on-resistance of 85 mOhm, keeping conduction losses low for loads up to 1.5 A. The switch integrates adjustable current limiting, over-temperature protection, and undervoltage lockout (UVLO), with a status flag output to signal fault conditions.

Slew rate control and fault protection

Slew-rate controlled turn-on limits inrush current into capacitive loads, reducing supply droop on the upstream rail. The adjustable current-limit threshold is set with an external resistor between the ILIM pin and ground, allowing the designer to tailor the trip point below the 1.5 A maximum. Over-temperature protection shuts off the switch if the junction exceeds the safe operating area, and UVLO prevents the switch from turning on when the input supply is too low.

Frequently asked questions

What is the exact difference between TPS2553DBVR-1 and TPS2553DBVR?

The TPS2553DBVR-1 and TPS2553DBVR share the same base product number TPS2553, package (SOT-23-6), and key ratings (1.5 A, 85 mOhm, adjustable current limit). The '-1' suffix typically indicates a specific factory-programmed current-limit threshold or a minor revision; the datasheet should be consulted for the exact threshold difference, as the pinout and footprint are identical.

Can TPS2553DBVR-1 be used as a replacement for TPS2553DBVR?

Yes, the TPS2553DBVR-1 is pin-compatible and functionally equivalent to the TPS2553DBVR in the same SOT-23-6 package. The only difference is the factory-set current-limit threshold; verify that the '-1' variant's limit matches your design requirement before substituting.

Does TPS2553DBVR-1 have adjustable current limit and how to set it?

Yes, the TPS2553DBVR-1 features an adjustable current limit. An external resistor connected from the ILIM pin to ground sets the threshold; the resistor value is chosen per the formula in the datasheet to trip below the 1.5 A maximum output current.

What is the maximum output current for TPS2553DBVR-1?

The TPS2553DBVR-1 is rated for a maximum continuous output current of 1.5 A.
