A multi-function feedback sense input in an electronic ballast control indicates a number of lamp faults on the basis of lamp parameters exceeding specified thresholds. An end of life detection is achieved by conditioning a lamp feedback with a DC offset to provide a simple threshold comparison to determine if the lamp exceeds specified operational boundaries. An open filament, absent lamp or broken cathode is detected on the same feedback sense by detecting an open circuit in the lamp filament and driving the sense feedback to a shutdown state in the event of a filament open circuit. The ballast control includes a current sense feedback for detecting overcurrent conditions as well as lamp faults so that the control detects an end of life condition, lamp absence, broken lamp, open filament, broken cathode, overcurrent, hardswitching or failure to ignite fault with a minimum number of feedback sensors. The ballast control provides a number of protections with a simplified circuit to reduce cost and improve functionality of the electronic ballast control.

An electronic ballast having end of lamp life and overheating protection, and automatic reignition and multiple striking capabilities includes AC/DC rectifier, PFC/boost, inverter, and ballast protection and control circuits. The ballast protection and control circuit is operable to place the ballast in a protected state when the lamp load connected to the ballast reaches an end of lamp life condition or the ballast overheats. The ballast protection and control circuit also automatically ignites the lamp load when it is connected to the ballast and generates multiple striking attempts for hard to strike lamp loads. The ballast may be connected to AC or DC power sources and different types of lamp loads, and may include various different types of inverter circuits.
