TPS2553DBVT-1 +BOM

Compact and highly efficient power switch solution for USB application

TPS2553DBVT-1 General Description

Product TPS2553DBVT-1 is a versatile power-distribution switch designed to handle precision current limiting in various applications. With a continuous load current capacity of up to 1.5 A, this device is ideal for situations involving heavy capacitive loads or short circuits. The TPS255x and TPS255x-1 series offer a programmable current-limit threshold, allowing users to set values between 75 mA and 1.7 A through an external resistor. The tight current-limit accuracy of ±6% at higher settings ensures precise control over power distribution

Key Features

  • TPS2553DBVT-1 is a load switch with an adjustable current limit
