Programmable protection set — what you can tune
Six programmable features are on the pin list: circuit breaker threshold, current limit, fault timeout, overvoltage protection (OVP), slew rate, and undervoltage lockout (UVLO). 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.
