Product Overview

The TPS2556DRBT is a Power Distribution Switch intended for applications where precision current limiting is required or heavy capacitive loads and short circuits are encountered. These devices offer a programmable current-limit threshold between 500mA and 5.0A (typical) via an external resistor. The power-switch rise and fall times are controlled to minimize current surges during turn on/off. TPS2556 device limit the output current to a safe level by switching into a constant-current mode when the output load exceeds the current-limit threshold. The FAULT logic output asserts low during overcurrent and over temperature conditions.
  • ±6.5% Current-limit accuracy at 4.5A
  • 3.5µS (typical) Fast overcurrent response
  • 2µA Maximum standby supply current
  • Built-in soft-start
