The TPS2553DBVRG4 from Texas Instruments is a power distribution switch designed for applications where precise current limiting is essential, or where heavy capacitive loads and short circuits are encountered. It provides up to 1.5 A of continuous load current.
Key electrical specifications include an adjustable current limit ranging from 75 mA to 1.7 A, with a typical accuracy of 7.5% at 1 A and ±6% at 1.7 A. The device operates over an input voltage range of 2.5 V to 6.5 V and features a low typical on-resistance of 85 mΩ. It includes features like active-high enable and reverse input-output voltage protection.
This power switch is suitable for various applications, including USB power switches and systems requiring controlled power delivery. It meets USB current-limiting requirements and is backwards compatible with previous versions like the TPS2550 and TPS2551.
The TPS2553DBVRG4 is available in SOT-23 and WSON packages, both designed for surface mounting. It operates within a temperature range of -40°C to 125°C and includes 15 kV ESD protection per IEC 61000-4-2.
The input voltage range is 2.5 V to 6.5 V.
