  • 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.

    TPS2554EVM-010 — 適用於 TPS2554 精密可調整、電流限制配電開關的評估模組

    The TPS2554EVM-010 is an evaluation module (EVM) for Texas Instruments TPS2554DRC and TPS2555DRC precision adjustable, current-limited power-distribution switches. This EVM operates over a 4.5 V to 5.5 V range. An onboard jumper sets the output current-limit to either 1.2 A or 2.4 A. Test points (...)
