What is LTC4367HMS8#TRPBF used for?
LTC4367HMS8#TRPBF protects sensitive downstream electronics in industrial power entry circuits where supply rails may experience transient overvoltages from load dumps, cable faults, or incorrect supply connections up to 100 V. It is commonly used in front-end protection stages of PLC modules, motor drive controllers, and test equipment power inputs that must survive harsh power bus conditions. The adjustable thresholds also make it suitable for multicell battery-powered systems requiring both overvoltage and undervoltage lockout at precisely defined levels.

Frequently Asked Questions
Up to what input voltage can LTC4367HMS8#TRPBF protect downstream circuits, and what external component controls the load current?
LTC4367HMS8#TRPBF is rated for input voltages up to 100 V on its supply and sense pins, making it suitable for industrial 48 V and automotive 60 V transient environments. It controls an external MOSFET, which handles the actual load current path; the IC provides the gate drive and fault detection logic, allowing the designer to choose a MOSFET sized for tens of amps or more without changing the controller IC.
What is the purpose of the 32 ms turn-on delay in LTC4367HMS8#TRPBF and how can it be customized?
The 32 ms on-delay prevents the protected load from connecting immediately after a valid supply is detected, allowing the input capacitors to charge and stabilizing the bus voltage before the downstream circuits power up. This reduces inrush current spikes that could trip upstream fuses or cause voltage droop on shared power rails. The delay is set by an external capacitor on the timer pin, so designers can extend it beyond 32 ms for particularly capacitive loads or slow-start requirements.
How are the overvoltage and undervoltage thresholds set on LTC4367HMS8#TRPBF, and what accuracy can be expected?
LTC4367HMS8#TRPBF uses external resistor dividers connected to its OV and UV comparator pins to set the trip thresholds at any voltage within the 100 V input rating. The internal reference voltage that the dividers compare against is factory-trimmed for precision, typically achieving threshold accuracy within a few percent, which is sufficient to protect circuits with ±10% supply tolerance windows commonly found in 24 V and 48 V industrial systems.
