The switch enters constant-current mode when the load exceeds the limit, pulling the open-drain fault flag low. Over-temperature shutdown and under-voltage lockout (UVLO) complete the protection suite. The slew-rate controlled turn-on prevents inrush current from tripping the upstream supply or causing bus voltage droop on capacitive loads — a common pain point in hot-plug and USB port designs.","metaTitle":"TPS2553DBVR Power Distribution Switch, 1.5 A, SOT-23-6","metaDescription":"Texas Instruments TPS2553DBVR high-side power switch, 1.5 A output, 85 mOhm Rds(on), adjustable current limit, SOT-23-6.

A single resistor between the ILIM pin and GND programs the overcurrent threshold. The exact resistor value is calculated from the desired limit using the formula in the datasheet — no external Vcc supply is needed because the device does not require Vcc/Vdd."},{"question":"Can TPS2553DBVR be used for 5 V USB power switching?","answer":"Yes. The 2.5 V to 6.5 V load supply range covers the 5 V USB bus, and the adjustable current limit can be set to 1.5 A or below to meet USB port requirements. The slew-rate controlled turn-on and overcurrent flag align with USB 2.0 hot-plug behaviour, though the part is not formally USB-IF certified."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS2553DBVR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS2553DBVR when reusing this data.
