It lets you insert a card into a live backplane without glitching the rail — the inrush current gets shaped by the programmable slew rate, and the circuit breaker trips if the load pulls past the threshold. No internal switch here; you pair it with external N-channel MOSFETs sized for your load current. Two channels means you can sequence two independent rails — say 5V and 3.3V — with a single controller, saving board space over two separate hot swap ICs. The 5 µA supply current keeps the always-on housekeeping power negligible. Operating temperature covers -40°C to 85°C, so it fits industrial environments: motor drives, factory automation panels, outdoor telecom cabinets. The supply range accepts 3V to 13V on one channel and 3V to 5.5V on the other, matching common backplane voltages. ## Programmable protection — what you can set Three programmable features give you control over the insertion event: circuit breaker threshold, fault timeout, and output slew rate. The circuit breaker sets the overcurrent trip point; the fault timeout decides how long the controller waits before declaring a fault; the slew rate ramps the output voltage to limit inrush. UVLO is built in — the part stays off until the input rail crosses the undervoltage threshold, then enables the gate drive. Latched fault means once the breaker trips, the controller stays off until you cycle power or toggle the enable — no automatic retry. That is the right behaviour for a backplane where a persistent short needs human intervention, not a power-cycle race. ## Lifecycle and sourcing ROHS3 compliant, so it passes current European and Asian environmental directives.","metaTitle":"TPS2301IPWG4 Hot Swap Controller, 2-Ch, 20-TSSOP, Active","metaDescription":"TI TPS2301IPWG4 dual hot swap controller with UVLO, circuit breaker, and slew rate control. 5 µA supply, -40 to 85°C.

Texas Instruments lists it as current production (ROHS3 compliant). No end-of-life notice or last-time-buy window — it can be designed into new BOMs without near-term obsolescence risk."},{"question":"What is the difference between TPS2301IPWG4 and TPS2301IPW?","answer":"The suffix G4 denotes ROHS3 compliance — the TPS2301IPW is an earlier ROHS version. Electrically and functionally identical: same dual hot swap controller, same programmable features, same 20-TSSOP package. The G4 variant is the current environmental-compliant release."},{"question":"Does TPS2301IPWG4 have UVLO and what are the thresholds?","answer":"Yes, UVLO is a standard feature. The exact rising and falling thresholds are specified in the datasheet; the part stays disabled until the input voltage rises above the UVLO rising threshold, then enables the gate drive. Below the falling threshold it resets the controller."},{"question":"What is a suitable equivalent for TPS2301IPWG4?","answer":"Within the same family, the TPS2300 is a single-channel variant (same package, same programmable features, same supply range). For a dual-channel hot swap controller with similar feature set, the TPS2301IPW (non-G4 ROHS) is the direct electrical equivalent. No pin-compatible second source from another manufacturer is listed."},{"question":"What does a hot swap controller do?","answer":"A hot swap controller manages the inrush current when a circuit board is plugged into a live backplane. It ramps the output voltage slowly (programmable slew rate), monitors for overcurrent (circuit breaker), and disables the output if a fault persists (fault timeout). This prevents glitches, blown fuses, and connector damage during live insertion."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS2301IPWG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS2301IPWG4 when reusing this data.
