What are the key features of LTC4367CMS8#TRPBF?
- 100 V rated overvoltage, undervoltage, and reverse polarity protection controller in a single 8-pin MSOP package
- Adjustable OV and UV thresholds via external resistor dividers allow flexible protection windows from near 0 V to 100 V
- Programmable 32 ms power-on turn-on delay filters transient surges before enabling the external pass MOSFET
What is LTC4367CMS8#TRPBF used for?
The LTC4367CMS8#TRPBF is deployed as a supply fault protection controller in industrial and automotive equipment where input rails may experience overvoltage surges up to 100 V, undervoltage dropouts, or reverse polarity connections. It is commonly used in 12 V to 72 V DC bus systems, field-instrumentation inputs, and high-reliability power entry circuits to protect sensitive downstream ICs. The adjustable thresholds and programmable 32 ms delay make it suitable for battery-backed systems and hot-swap supply applications.

Frequently Asked Questions
What voltage events does the LTC4367CMS8#TRPBF protect against, and what is its maximum rated input voltage?
The LTC4367CMS8#TRPBF protects downstream circuits against three types of supply faults: overvoltage (OV), undervoltage (UV), and reverse polarity. It is rated to operate with input voltages up to 100 V, covering industrial 48 V bus systems and automotive load-dump transients. When any fault condition is detected, the device turns off the external N-channel pass MOSFET to isolate the downstream load within microseconds.
How are the overvoltage and undervoltage thresholds set on the LTC4367CMS8#TRPBF?
The OV and UV trip points are set by external resistor dividers connected to dedicated threshold pins on the LTC4367CMS8#TRPBF. Users can program independent OV and UV windows anywhere within the 0 V to 100 V input range using standard 1% resistors, providing design flexibility for 12 V, 24 V, or 48 V systems without factory customization. This adjustable threshold architecture enables a single part to serve multiple rail voltages.
Why does the LTC4367CMS8#TRPBF include a 32 ms turn-on delay, and how is it used in practice?
The 32 ms power-on delay prevents the downstream circuit from being enabled during input voltage transients, inrush events, or brief supply glitches that would otherwise trigger false fault conditions. In practice, the 32 ms blanking window ensures the supply is stable for at least 32 milliseconds before the external N-channel pass MOSFET is turned on, avoiding nuisance shutdowns in 12 V or 48 V systems with capacitive inrush or startup ringing.
What external MOSFET type does the LTC4367CMS8#TRPBF drive, and what package does the controller itself use?
The LTC4367CMS8#TRPBF drives an external N-channel MOSFET, which acts as the series pass element in the input protection circuit. The gate drive is designed to accommodate N-channel devices with gate thresholds below the controller supply voltage. The controller itself is packaged in an 8-pin MSOP (micro small-outline) with a 0.65 mm lead pitch, making it suitable for compact PCB layouts on industrial field instruments and power entry modules.
