Product details

Hot swap controller for 9V to 80V rails

It operates from a 9V to 80V supply range, suiting it for 12V, 24V, and 48V telecom, industrial, and automotive power distribution systems. The controller drives an external N-channel MOSFET — no internal switch — so the pass element and its heatsinking are sized separately for the load current. The 1.3 mA supply current is drawn from the input rail and is independent of the load.

Programmable protection and auto-retry behaviour

Four programmable protection thresholds are set with external resistors: current limit, fault timeout, overvoltage protection (OVP), and undervoltage lockout (UVLO). The -2 variant implements an auto-retry cycle after a fault timeout — the controller attempts to restart after a cooling period, which is useful for transient overloads that clear themselves. The 10-VSSOP package (3.00 mm × 3.00 mm body) is a surface-mount footprint compatible with standard reflow profiles.

NRND status — plan the replacement now

This means Texas Instruments has flagged the part for eventual discontinuation; new designs should target a pin-compatible alternative within the LM5069 family or a newer-generation hot swap controller.

Frequently asked questions

Is the LM5069MM-2 obsolete or NRND?

It is not yet fully discontinued, but Texas Instruments advises against using it in new designs. Existing production can continue while supply lasts through independent channels.

What is the difference between LM5069MM-1 and LM5069MM-2?

The primary difference is the fault response behaviour. The LM5069MM-1 latches off after a fault timeout and requires a power cycle or enable toggle to restart. The LM5069MM-2 implements an auto-retry cycle — it attempts to restart after a cooling period, which suits applications where transient overloads are expected to clear.

What is the LM5069MM-2 used for?

It is a hot swap controller for live-insertion of circuit boards into a powered backplane. Typical applications include telecom line cards, industrial PLC modules, and automotive power distribution where a 9V to 80V rail must be protected against inrush current, overcurrent, and overvoltage faults.
