It delivers up to 250 mA continuous output from a load supply of 2.7 V to 5.5 V, with a typical on-resistance of 80 mOhm. The switch is controlled by an On/Off logic input (non-inverting) and requires no separate Vcc supply — the gate drive is self-biased from the load voltage. Built-in fault protection includes fixed current limiting, over-temperature shutdown, and undervoltage lockout (UVLO), with a status flag output to signal fault conditions to the host controller. The operating junction temperature range of -40°C to 125°C suits industrial, automotive, and outdoor equipment environments where the switch must handle variable ambient temperatures and moderate loads. ## Fault protection set: current limit, thermal shutdown, UVLO The TPS2055D integrates three protection mechanisms that reduce external component count. Current limiting is fixed (non-adjustable) and engages when the output exceeds the threshold, holding the current to a safe level. Over-temperature shutdown (OTP) protects the die if the junction exceeds the thermal limit — the switch latches off and the status flag asserts. UVLO disables the switch if the input voltage drops below the minimum operating level, preventing the pass FET from operating in its linear region. The status flag output (open-drain, active low) can drive a GPIO or interrupt input on the system controller for diagnostic feedback. ## Active lifecycle — no LTB risk for production BOMs The TPS2055D carries an Active product status with ROHS3 compliance.","metaTitle":"TPS2055D Power Distribution Switch, 80mOhm, 250mA, 8-SOIC","metaDescription":"TI TPS2055D high-side power switch: 80mOhm Rds(on), 250mA output, fault protection (current limit/OTP/UVLO), -40°C to 125°C, 8-SOIC.

If the junction temperature exceeds the thermal limit, the switch turns off and the status flag asserts."},{"question":"Is TPS2055D RoHS compliant?","answer":"Yes, the TPS2055D is ROHS3 compliant, meeting the latest RoHS directive requirements for lead-free and restricted-substance materials."},{"question":"Is TPS2055D suitable for USB supply?","answer":"The TPS2055D operates from a 2.7 V to 5.5 V load supply and delivers up to 250 mA, which covers USB 2.0 low-power and full-speed port requirements (100 mA / 500 mA per port with appropriate current limiting). The 80 mOhm Rds(on) ensures minimal voltage drop on the 5 V rail. However, for a standard downstream USB port requiring 500 mA, verify that the fixed current-limit threshold meets your design margin — the TPS2055E variant with a higher limit may be more appropriate for 500 mA applications."},{"question":"What is the difference between TPS2055D and TPS2055E?","answer":"The TPS2055D and TPS2055E are pin-compatible high-side switches in the same family. The primary difference is the fixed current-limit threshold: the TPS2055D is set for lower current (250 mA max output), while the TPS2055E typically has a higher trip point suitable for 500 mA USB ports. Both share the same 8-SOIC package, 80 mOhm Rds(on), and protection feature set. Choose the D version for sub-250 mA loads and the E version for higher-current rails."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS2055D","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS2055D when reusing this data.
