What are the key features of LTC4368CMS-2#PBF?
- Protects against overvoltage, undervoltage, overcurrent, and reverse polarity up to 100 V
- -3 mV reverse supply threshold for accurate reverse current blocking
- Adjustable overvoltage and undervoltage thresholds via external resistors
- 10-pin MSOP package for compact power protection circuits
- Drives external N-channel MOSFET for low-loss series protection
What is LTC4368CMS-2#PBF used for?
The LTC4368CMS-2#PBF is designed for protecting sensitive downstream loads in industrial power supplies, telecom central office equipment, and automotive 12 V to 48 V bus systems from voltage surges and reverse polarity events up to 100 V. By controlling an external N-channel MOSFET, it limits inrush current and disconnects the load during fault conditions, preventing component damage. The adjustable threshold pins allow the designer to set precise over-voltage and under-voltage trip points for specific supply rail requirements.

Frequently Asked Questions
What is the maximum input voltage the LTC4368CMS-2#PBF can handle, and which fault conditions does it protect against?
The LTC4368CMS-2#PBF supports input voltages up to 100 V and protects downstream circuits against 4 fault types: overvoltage, undervoltage, overcurrent, and reverse supply polarity. The -3 mV reverse threshold provides precise reverse current detection without significant forward voltage drop. This comprehensive protection makes it suitable for 48 V telecom buses, 24 V industrial rails, and automotive systems where transients can exceed 60 V during load dumps.
How are the overvoltage and undervoltage thresholds set on the LTC4368CMS-2#PBF, and can they be tuned for a 24 V industrial bus?
The LTC4368CMS-2#PBF uses external resistor dividers on its OV and UV threshold pins to set programmable trip points across the full 100 V operating range. For a 24 V industrial bus, a designer can set the overvoltage threshold at 28 V and the undervoltage threshold at 20 V using standard 1% resistors, providing a ±4 V window around the nominal 24 V rail. This flexibility allows a single IC to be reused across multiple supply rail voltages by changing only the resistor values, reducing BOM complexity.
What external component does the LTC4368CMS-2#PBF require to implement the protection circuit, and why is an N-channel MOSFET preferred?
The LTC4368CMS-2#PBF drives an external N-channel MOSFET placed in series with the power path to control load connection and disconnection during fault events. N-channel MOSFETs are preferred over P-channel devices because they offer lower on-resistance (R_DS(on)) for a given die size, reducing power dissipation at high currents. For a 5 A load on a 48 V bus, using an N-channel FET with 10 mΩ R_DS(on) results in only 250 mW of conduction loss compared to several watts with an equivalent P-channel device.
