Key Features
- High-efficiency switching surge stopper protecting input rails from voltage transients up to the rated clamp level
- Adjustable fault threshold allowing designers to set overcurrent and overvoltage trip points via external resistors
- Single-channel input fault protection controller in a compact 12-pin MSOP (R-PDSO-G12) package
- Active clamp architecture limiting power dissipation during surge events compared to passive TVS solutions
Applications
The LTC7860EMSE#TRPBF is used in industrial power input protection circuits, hot-swap systems, and server PSU inputs where transient voltage surges must be clamped before reaching sensitive downstream DC-DC converters. Its adjustable threshold suits 12 V and 24 V rail protection in telecommunications equipment, industrial motor drives, and factory automation controllers. The switching architecture minimizes heat generation during surge events, enabling reliable long-term operation without large heatsinks.

Frequently Asked Questions
What type of protection does the LTC7860EMSE#TRPBF provide, and on how many input channels?
The LTC7860EMSE#TRPBF provides high-efficiency switching surge stopper and input fault protection on 1 channel, using an active switching clamp to suppress voltage transients and limit overcurrent on the input rail. This protects downstream DC-DC converters and load circuits from damage during power-line surge events.
What package does the LTC7860EMSE#TRPBF use, and how does it fit into a compact PCB design?
It uses a 12-pin MSOP (JESD-30 code R-PDSO-G12) package with a body width of approximately 3 mm and 0.65 mm pin pitch, offering a very small PCB footprint for input protection functions. This compact form factor suits space-constrained industrial boards, telecom cards, and server power modules where a full-size IC would be impractical.
How does the adjustable threshold feature of LTC7860EMSE#TRPBF benefit different power rail protection designs?
The adjustable threshold allows engineers to set the overcurrent and overvoltage trip points using external resistors, enabling the same IC to protect 12 V, 24 V, or 48 V input rails without redesigning the core circuit. This flexibility reduces BOM complexity when the same board revision must support multiple supply voltages in industrial or telecommunications applications.
Why is a switching surge stopper like LTC7860EMSE#TRPBF preferred over a passive TVS diode for input rail protection?
Unlike a passive TVS diode that dissipates surge energy as heat — requiring large diodes for high-energy transients — the LTC7860EMSE#TRPBF uses an active switching clamp that limits current actively, reducing power dissipation to a fraction of a watt during typical surge events. This allows protection of input rails up to the rated clamp voltage with a 12-pin MSOP IC and minimal passive components, eliminating bulky heatsinks.
