Product details

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.

Frequently asked questions

Does LTC4231HUD-2#PBF have auto-retry?

Yes, the -2 variant includes auto-retry. After a fault, the controller will attempt to restart the output rather than latching off.

Where can I buy LTC4231HUD-2#PBF and how do I get a price?

This part is available to order through independent distribution. Submit an RFQ for current pricing and availability — confirmed at quote time, no stock count or price displayed here.

What is the difference between LTC4231HUD-1 and LTC4231HUD-2?

The -1 variant typically latches off after a fault, requiring a power cycle or enable toggle to restart. The -2 variant (this part) includes auto-retry, so it will automatically attempt to restart after a fault timeout. The pinout and package are the same.

When sourcing LTC4231HUD-2#PBF, what is the closest functional second-source?

The LTC4231HMS-2#PBF is a functionally identical part with the same programmable features, auto-retry, and supply range, but in an MSOP-12 package instead of the 12-QFN. Verify the footprint compatibility before substituting.
