Surge Suppression ICS FAQ

How does the LTC4380 provide overvoltage protection?

It protects the load by clamping the gate voltage of an external N-channel MOSFET, limiting the output voltage to a safe value during overvoltage events.

What is the function of the TMR pin?

An internal multiplier generates a current on the TMR pin proportional to V_DS and I_D, enabling overcurrent and overvoltage protection based on MOSFET stress.
