Its 9V to 72V supply range covers the common telecom -48V rail, 24V industrial buses, and 12V automotive systems, making it a general-purpose choice for any application where a board must be plugged into a powered slot without glitching the shared supply. The controller does not integrate the pass switch — it drives an external N-channel MOSFET, so the current rating scales with the FET you pair it with. ## Key ratings and what they mean for the BOM The 9V to 72V input range is the primary selection gate: a 48V telecom design sees plenty of headroom for transients, while a 12V automotive board still has margin above the nominal rail. The 1 mA supply current is the controller's own draw, negligible against the load current the external FET handles — it matters for standby power budgets but not for the main thermal calculation. Programmable UVLO lets you set the undervoltage lockout threshold with a resistor divider, so the controller stays off until the input rail is stable, preventing the FET from turning on during a brownout. The thermal limit feature protects the external FET by latching off if the die temperature exceeds the threshold — a useful safeguard when the load fault is a hard short that the current-limit loop alone cannot clear fast enough. ## Package and temperature grade Housed in a 6-TDFN 3x3 mm exposed pad package, the MAX5903NNETT+T is surface-mount. The exposed pad needs a thermal via stitch to the ground plane. Operating range is -40°C to 85°C. ## Lifecycle and sourcing The MAX5903NNETT+T carries an active lifecycle status and is ROHS3 compliant. For current pricing and availability, submit an RFQ — the quote will reflect the prevailing market conditions at the time of your request. No official second source or pin-compatible alternate is cited in the available records; if dual-sourcing is a requirement, the design should accommodate a functional equivalent from another vendor with a similar UVLO-programmable hot swap controller in the same supply range.","metaTitle":"MAX5903NNETT+T Hot Swap Controller, Simple Swapper, 9V-72V","metaDescription":"Maxim MAX5903NNETT+T hot swap controller, Simple Swapper series. 9V to 72V supply, thermal limit, UVLO programmable, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"Simple Swapper™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Type":"Hot Swap Controller","Series":"Simple Swapper™","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Thermal Limit","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"6-WDFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Supply":"1 mA","Voltage - Supply":"9V ~ 72V","Internal Switch(s)":"No","Number of Channels":"1","Operating Temperature":"-40°C ~ 85°C","Programmable Features":"UVLO","Supplier Device Package":"6-TDFN (3x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.24","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.24000","currency":"USD"},{"qty":10,"price":"$5.60100","currency":"USD"},{"qty":25,"price":"$5.29480","currency":"USD"},{"qty":100,"price":"$4.58890","currency":"USD"},{"qty":250,"price":"$4.35360","currency":"USD"},{"qty":500,"price":"$3.90648","currency":"USD"},{"qty":1000,"price":"$3.29462","currency":"USD"},{"qty":2500,"price":"$3.12989","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/713d1ef949327f85a7d09d2ebea02c0f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the MAX5903NNETT+T equivalent to any other hot swap controller?","answer":"No pin-compatible equivalent is cited in the available records.
