9 V to 80 V hot swap controller with power limiting, auto-retry fault response, MSOP-10
The Texas Instruments LM5069-2 is a positive hot swap controller for 9 V to 80 V rails that drives an external N-channel MOSFET to limit inrush current when boards are plugged into a live backplane. It programs both current limit and power limit to keep the MOSFET inside its safe operating area, and adds adjustable UVLO/OVLO, a circuit breaker and an open-drain power-good output. The -2 version auto-retries after a fault. It is used in 24 V / 48 V telecom, server and industrial backplanes. Lead times are extended; Cerametronics helps buyers locate traceable stock.

Quality & Traceability
Cerametronics is ISO 9001 certified and products are RoHS compliant, with counterfeit screening and full traceability on every shipment. A Certificate of Conformance is available on request. For allocation-sensitive or high-risk lots, independent third-party lab verification can be arranged — just flag it on your RFQ. Any lot that fails incoming inspection is quarantined and never shipped.
FAQ
What is the difference between LM5069MM-1 and LM5069MM-2?
They are pin-compatible. The -1 latches off after a fault and needs a power cycle or UVLO toggle to restart; the -2 retries automatically at a fixed duty cycle. Changing between them changes system fault behaviour.
What does /NOPB and MMX mean?
/NOPB marks the lead-free (RoHS) version. LM5069MM-2/NOPB is a 1,000-piece reel; LM5069MMX-2/NOPB is the larger reel of the same part.
