Key Features
- 100 V maximum input rating with adjustable overvoltage and undervoltage thresholds protects systems across a wide range of industrial and automotive supply voltages
- 0.5 ms programmable turn-on delay prevents transient supply spikes from triggering unnecessary load disconnect events in noisy power environments
- Single-channel controller in SOIC-8 integrates reverse supply, overvoltage, and undervoltage protection in one IC, eliminating discrete Schottky diodes and comparator circuits
Applications
The LTC4367IMS8-1#PBF is used in industrial automation equipment, telecommunications power supplies, and automotive 48 V systems where input rails are subject to surge events, reverse polarity, or brownout conditions. Its 100 V input capability and adjustable threshold resistors make it ideal for protecting DC-DC converters and sensitive analog circuitry in field-deployed instrumentation and motor drive controllers. Engineers deploy it in solar energy storage systems and military ground vehicle electronics where supply voltage excursions can damage or destroy unprotected loads.

Frequently Asked Questions
What is the maximum input voltage the LTC4367IMS8-1#PBF can withstand during a surge event?
The LTC4367IMS8-1#PBF is rated for up to 100 V at its input, allowing it to handle industrial surge events on 12 V, 24 V, and 48 V bus architectures without component damage. This 100 V capability exceeds the typical 60 V rating of many alternative protection controllers, providing extra headroom for load dump transients in automotive and heavy equipment power systems that can spike to 90 V or above.
How do the adjustable overvoltage and undervoltage thresholds improve system reliability in variable supply environments?
The LTC4367IMS8-1#PBF uses external resistor dividers to set both overvoltage and undervoltage trip points independently, allowing designers to define a valid supply window as tight as ±5% or as wide as 10 V to 72 V. This prevents nuisance disconnects from minor supply ripple while reliably isolating loads from fault conditions exceeding the programmed 100 V ceiling, maintaining over 99.9% uptime in telecom rectifier systems and industrial motor control cabinets with fluctuating utility power.
Why is a 0.5 ms turn-on delay important for protecting sensitive loads in industrial power systems?
A 0.5 ms turn-on delay lets the LTC4367IMS8-1#PBF ignore voltage transients shorter than 0.5 ms — such as relay contact bounce or capacitive inrush spikes on a 48 V bus — before enabling the protected load. Without this delay, a false OV trip could disconnect a microcontroller or FPGA mid-operation, causing data corruption or hardware reset. The 0.5 ms delay balances fast fault response with immunity to sub-millisecond transients common in switching power supply startup sequences.
