The auto-retry feature means the controller will repeatedly attempt to restart after a fault. ## Lifecycle and sourcing The LTC4231HUD-2#PBF is listed as Active and ROHS3 compliant. No last-time-buy notice or end-of-life indication is on record. For a BOM line that needs a hot swap controller with a wide input range and programmable protections, this part is a safe selection for new designs. Sourcing is through independent distribution; availability and current pricing are confirmed at quote time against an RFQ.","metaTitle":"LTC4231HUD-2#PBF Hot Swap Controller, 2.7V-36V, 12-QFN","metaDescription":"LTC4231HUD-2#PBF hot swap controller from Analog Devices. 2.7V to 36V supply, 4 µA supply current, -40°C to 125°C range.

The -2 variant (this part) includes auto-retry, so it will automatically attempt to restart after a fault timeout.
