The TPS2556-Q1 and TPS2557-Q1 power-distribution switches are specialized for automotive applications which require precision current limiting or capacity to handle heavy capacitive loads and short circuits. These devices offer a programmable current-limit threshold between 500 mA and 5 A (typical) via an external resistor. Control of the power-switch rise and fall times minimizes current surges during turnon or turnoff.

TPS2556-Q1 and TPS2557-Q1 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 overtemperature conditions.

Use with the TPS2511-Q1 or TPS2513A-Q1 for a low-loss, automotive-qualified, USB charging-port solution capable of charging all of today’s popular phones and tablets.

TPS2556DRBEVM-423 — TPS2556DRBEVM-423: Evaluierungsmodul für TPS2556

The TPS2556EVM-423 and TPS2557EVM-423 are evaluation modules (EVM) for Texas Instruments power-distribution switches with adjustable current-limit. These EVMs operate over a 2.5-V to 6.5-V range. An on-board jumper sets the output current-limit to either 0.5 A or 1 A. The board is designed for the (...)
