What are the key features of LTC4231IMS-2#PBF?
- Wide 2.7 V to 36 V input voltage range supports 12 V automotive, 24 V industrial, and 5 V telecom hot swap applications from a single controller IC
- N-channel low-side MOSFET control with adjustable current limiting protects backplane power rails during board insertion events
- 12-pin MSOP package with automotive-grade operation minimizes PCB footprint in space-constrained server blades and automotive ECU power management
What is LTC4231IMS-2#PBF used for?
The LTC4231IMS-2 enables safe hot swapping of plug-in modules in 12 V to 36 V power systems such as automotive ECUs, industrial backplanes, and telecom line cards where live board insertion would otherwise cause destructive inrush currents. Its adjustable current limit and controlled MOSFET turn-on ramp prevent supply rail collapse when cards are plugged into active systems. The automotive-grade temperature range and compact MSOP-12 package also suit in-vehicle power distribution units managing multiple PCIe or CAN module slots.

Frequently Asked Questions
What input voltage range does LTC4231IMS-2 support and which power rail standards does that cover?
The LTC4231IMS-2 operates from 2.7 V to 36 V input, covering 5 V USB-powered systems, 12 V automotive and server backplanes, and 24 V to 36 V industrial power rails in a single controller. This wide range eliminates the need for voltage-specific hot swap IC variants when a design spans multiple supply domains.
How does the LTC4231IMS-2 protect a backplane when a module is inserted while the supply is live?
The controller drives an external N-channel MOSFET with a controlled gate ramp, limiting inrush current to a user-set threshold defined by an external resistor typically in the 5 mΩ to 50 mΩ range. This clamps peak inrush current below the backplane bus capacitor's safe charge current, preventing voltage dips exceeding 100 mV that would otherwise reset adjacent cards.
When is LTC4231IMS-2 preferred over a PTC fuse for hot swap protection in an automotive ECU rack?
A PTC fuse requires 10 ms to 100 ms to respond and cannot reset electronically, requiring manual intervention after a fault. The LTC4231IMS-2 responds in under 1 µs to overcurrent events and auto-retries after clearing, enabling the ECU slot to return to service automatically. The 36 V rating also handles load dump transients common in 12 V automotive environments without requiring an additional TVS clamp.
