What is Hiccup Mode / Hiccup Protection?

Hiccup mode is a form of over current protection that is available in certain power supplies and LED Drivers. The advantage to Hiccup Mode or Hiccup protection is that when an output overcurrent or short is detected the driver/supply will enter into “Hiccup Mode” and will stay in this mode protecting the supply until the fault is removed. Once the fault is removed the supply will resume normal operation without having to cycle the power as you would do with many latching protection circuits.

While there is not a specific callout in our filters for Hiccup mode you will find supplies and drivers listed with OCP (Over Current Protection) in the features box.

When looking in the datasheet for these drivers/Supplies you will see the type of overcurrent protection.
