Applications
The LTC4367HMS8#PBF is designed for protecting sensitive electronics in industrial, automotive, and telecom power supply systems where overvoltage surges, undervoltage brownouts, and reverse supply connections can occur. By controlling an external N-channel MOSFET, it isolates the load instantly upon a fault, preventing damage to downstream ICs without requiring bulky passive clamping components. Its adjustable thresholds and 32 ms on-delay make it adaptable to a wide range of supply rail voltages from 2.9V to 100V.

Frequently Asked Questions
What voltage protection range does LTC4367HMS8#PBF support and how are the thresholds set?
The LTC4367HMS8#PBF supports supply voltages up to 100V and provides adjustable overvoltage (OV) and undervoltage (UV) thresholds configurable via external resistor dividers connected to the threshold pins. This flexibility lets designers tailor protection windows precisely for 5V, 12V, 24V, or 48V bus rails commonly used in industrial and telecom power systems.
Why does LTC4367HMS8#PBF use a 32 ms turn-on delay and how does it benefit system reliability?
The 32 ms turn-on delay on the LTC4367HMS8#PBF prevents the controlled MOSFET from enabling during supply ramp-up transients that momentarily violate the OV or UV thresholds. This avoids nuisance trips and ensures the downstream load only sees power once the supply voltage has stabilized within the defined ±threshold window, improving reliability in systems with soft-start power supplies or long cable runs.
How does LTC4367HMS8#PBF handle reverse polarity conditions compared to a simple diode-based solution?
The LTC4367HMS8#PBF detects reverse supply polarity and keeps the external N-channel MOSFET off, preventing reverse current from flowing into the load, much like a series diode but without the 0.5V to 0.7V forward voltage drop that wastes power. At 1 A load current, eliminating the diode drop can save 0.5W to 0.7W of dissipation, improving efficiency in high-current 5V or 12V systems with reverse connection risk.
