What are the key features of LTC4368IDD-1#PBF?
- 100V overvoltage protection rating with adjustable OV, UV, and OC thresholds enabling flexible protection tuning for 12V, 24V, 48V, and up to 100V industrial power rails
- -50mV reverse voltage threshold prevents reverse supply damage, protecting downstream ICs from incorrect polarity connection without requiring an external diode
- Combined OV/UV/OC and reverse-supply protection in a single 10-pin DFN device reduces external component count versus discrete protection solutions
- Single-channel architecture with adjustable threshold support covers a wide range of industrial, telecom, and automotive power protection requirements
What is LTC4368IDD-1#PBF used for?
The LTC4368IDD-1#PBF is designed to protect sensitive electronic loads from overvoltage transients, undervoltage brownouts, overcurrent faults, and accidental reverse supply connections in industrial power distribution, telecommunications equipment, and server infrastructure. Its 100V rating makes it suitable for 48V telecom bus systems, 24V industrial rails, and automotive applications where load dump transients can exceed normal operating voltages. The adjustable thresholds allow a single device to be configured for multiple system voltage levels, reducing the number of unique BOM line items across product families.

Frequently Asked Questions
What protection functions does LTC4368IDD-1#PBF integrate, and what is its maximum rated operating voltage?
The LTC4368IDD-1#PBF integrates four protection functions in one device: overvoltage (OV), undervoltage (UV), overcurrent (OC), and reverse supply protection. The controller supports rails up to 100V, making it suitable for 48V telecom bus, 24V industrial, and automotive load dump scenarios where transients can significantly exceed the nominal supply voltage.
How does the -50mV reverse threshold of LTC4368IDD-1#PBF protect against reverse polarity conditions?
The -50mV reverse threshold means the device detects a reverse supply condition when the input voltage drops 50 mV below the output (or ground reference). At that point, it disables the external pass FET, blocking reverse current flow. This protects downstream ICs from damage due to reverse polarity wiring errors without requiring a series Schottky diode, which would add forward voltage drop and power dissipation.
Are the protection thresholds of LTC4368IDD-1#PBF adjustable, and how does this help across different power rail voltages?
Yes, the OV, UV, and OC thresholds are all externally adjustable via resistor dividers connected to the threshold pins. This allows a single LTC4368IDD-1#PBF design to be reprogrammed for 12V, 24V, or 48V rails simply by changing 2 to 3 resistors, eliminating the need for separate protection ICs for each voltage level and reducing design time and inventory complexity.
For a 48V telecom rectifier output feeding sensitive DSP loads, what external components does LTC4368IDD-1#PBF require to form a complete protection circuit?
A typical application requires an external N-channel MOSFET rated for at least 100V and the required load current (e.g., 60V 10A), a current-sense resistor (typically 10 mohm to 100 mohm) in series with the power path for OC detection, and resistor dividers (typically 100 kohm range) to set the OV and UV thresholds for the 48V bus. The DFN-10 controller IC handles all threshold comparison, gate driving, and fault latching logic internally.
