Frequently Asked Questions
Can this device be used in life support systems?
No, these products are not designed for use in life support appliances, devices or systems where malfunction could result in personal injury.
What type of overload protection is available for the TOPFET?
The unit supports internal overload protection triggered by high power dissipation and external overload through sensing components.
What should I know about overvoltage transients when using this device?
When operating above 50V, the dedicated power MOSFET actively turns on to clamp overvoltage transients.
Is continuous operation possible if the junction temperature is exceeded?
No, the maximum continuously rated junction temperature (Tj) is 150°C.
