Key Features
- 100 V overvoltage protection rating guards high-voltage industrial and telecom power rails
- Integrated OV, UV, OC, and reverse supply protection in a single-channel controller
- -3 mV adjustable reverse threshold provides precise reverse voltage detection without false triggers
- MSOP-10 surface-mount package minimizes PCB footprint in compact protection circuit designs
Applications
The LTC4368CMS-2#TRPBF is designed to protect sensitive downstream electronics in industrial power systems, telecom line cards, and automotive 48 V battery systems where the input supply can experience overvoltage transients up to 100 V, undervoltage dropouts, overcurrent faults, or reverse polarity conditions. Its adjustable threshold architecture allows engineers to tune the OV and UV trip points precisely for the supply rail in use, reducing false shutdowns while ensuring fast fault response. The device is also suitable for protecting power entry circuits in ruggedized field instruments and high-voltage data acquisition modules exposed to harsh electrical environments.

Frequently Asked Questions
What maximum input voltage does the LTC4368CMS-2#TRPBF protect against in industrial power systems?
The LTC4368CMS-2#TRPBF is rated for overvoltage protection up to 100 V, making it suitable for protecting power entry circuits in industrial 48 V and 72 V DC bus systems where transient spikes can exceed the nominal rail by 50 V or more. This 100 V rating provides substantial margin over 48 V telecom systems, ensuring the downstream load remains protected even during severe inductive switching transients.
How does the -3 mV reverse threshold of the LTC4368CMS-2#TRPBF improve reverse polarity protection compared to a simple diode?
The LTC4368CMS-2#TRPBF detects reverse supply conditions at a -3 mV adjustable threshold, triggering immediate FET shutoff before reverse current can damage downstream circuits — far faster and with lower forward voltage drop than a Schottky diode reverse protection scheme. Unlike a diode that dissipates power proportional to forward voltage at full load current, the controller-driven FET approach reduces conduction loss to milliohms, improving efficiency in 5 A to 20 A load circuits.
Which protection modes does the LTC4368CMS-2#TRPBF integrate, and how does this reduce external component count?
The LTC4368CMS-2#TRPBF integrates overvoltage, undervoltage, overcurrent, and reverse supply protection in a single-channel controller IC, eliminating the need for separate OV clamp, UV lockout, and reverse blocking circuits that would otherwise require 4 or more discrete ICs and associated resistor dividers. This integration reduces BOM complexity and PCB area by 60% or more compared to discrete protection solutions in 24 V to 100 V industrial power entry designs.
In which package does the LTC4368CMS-2#TRPBF come, and how many pins does the protection circuit require?
The LTC4368CMS-2#TRPBF is housed in an MSOP-10 surface-mount package with 10 pins, occupying a footprint of approximately 3 mm × 3 mm on the PCB. The 10-pin configuration provides dedicated connections for the gate drive, fault flag, enable input, and adjustable threshold pins, giving designers full control of OV, UV, and OC trip points through external resistor dividers without requiring additional circuitry.
