Introduction

AI Translation

The TPS2554/55 power-distribution switches are 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 500 mA and 2.5 A (typ) via an external resistor. TPS2554/55 devices 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.
