产品描述

The TPS2556/57 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 5.0 A (typ) via an external resistor. The power-switch rise and fall times are controlled to minimize current surges during turn on/off.

TPS2556/57 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.
