Its -9V to -100V supply range covers the standard -48V telecom bus and the -72V nominal used in some industrial power architectures. Drawing only 500 µA from the supply rail, the controller's own power dissipation is negligible even in dense line-card designs where thermal budget is tight. ## Programmable protection and fault handling The controller integrates a programmable circuit breaker, current limit, slew rate control, and UVLO — all set with external resistors or capacitors. The auto-retry and latched fault options let the designer choose between automatic recovery after a fault clears or a hard latch that requires a power-cycle reset. A fault timeout prevents the controller from staying in current limit indefinitely, protecting both the pass element and the load. The thermal limit shuts down the internal switch if the die temperature exceeds the safe operating area, adding a second layer of protection beyond the electrical limits. ## Package, temperature grade, and sourcing Analog Devices lists this part as Active in its lifecycle.","metaTitle":"MAX5901LAETT+ Hot Swap Controller, -9V to -100V","metaDescription":"MAX5901LAETT+ from Analog Devices, Simple Swapper series hot swap controller. -9V to -100V supply, 500 µA supply current, 6-TDFN package.","metaKeywords":null},"attributes":{"series":"Simple Swapper™","packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Hot Swap Controller","Series":"Simple Swapper™","Package":"Bulk","Features":"Auto Retry, Fault Timeout, Latched Fault, Thermal Limit, UVLO","Applications":"Networking","Mounting Type":"Surface Mount","Package / Case":"6-WDFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Supply":"500 µA","Voltage - Supply":"-9V ~ -100V","Internal Switch(s)":"Yes","Number of Channels":"1","Operating Temperature":"-40°C ~ 85°C (TA)","Programmable Features":"Auto Retry, Circuit Breaker, Current Limit, Fault Timeout, Latched Fault, Slew Rate, UVLO","Supplier Device Package":"6-TDFN-EP (3x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.23","stockQuantity":0,"priceTiers":[{"qty":245,"price":"$1.23000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/999ad8ddc5b5f69cff4770c683284b52.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does the MAX5901LAETT+ include an internal MOSFET?","answer":"Yes, the device has an internal switch, so no external MOSFET is required for the basic hot-swap function in many applications."},{"question":"What protection features are programmable on this hot swap controller?","answer":"The MAX5901LAETT+ offers programmable circuit breaker, current limit, fault timeout, slew rate, and UVLO.
