Product Overview

The TPS2553DBVR is an Adjustable Active High Current-limited Power Distribution Switch intended for applications where precision current limiting is required or heavy capacitive loads and short-circuits are encountered and provide up to 1.5A of continuous load current. This constant current device offers a programmable current-limit threshold between 75mA and 1.7A (typical) via an external resistor. Current-limit accuracy as tight as ±6% can be achieved at the higher current-limit settings. The power-switch rise and fall times are controlled to minimize current surges during turn on/off. TPS2553 device limit the output current to a safe level by using a constant-current mode when the output load exceeds the current-limit threshold. An internal reverse-voltage comparator disables the power-switch when the output voltage is driven higher than the input to protect devices on the input side of the switch. The FAULT output asserts low during over-current and reverse-voltage conditions.
  • Up to 1.5A maximum load current
  • ±6% Current-limit accuracy at 1.7A (typical)
  • Meets USB current-limiting requirements
  • Backwards compatible with TPS2550/51
  • 75 to 1300mA Typical adjustable current limit
  • Constant-current device
  • Fast over-current response (2µs typical)
  • 85mΩ High-side MOSFET
  • Reverse input-output voltage protection
  • 2.5 to 6.5V Operating range
  • Built-in soft-start
  • Green product and no Sb/Br
