Circuit Protection for HBLED String
The preferred method of driving LEDs is to have them in strings of LEDs in series, so that currents in the strings are matched for equal brightness.

Features
- High ON-state current capability
- Low off-state leakage
- Ability to auto-reset to off-state if LED heals
- Low and repeatable response time
Key Requirement
- Low ON-state resistance, high OFF-state resistance and high reliability
Benefits
- High reliability, enables longevity of string and fixture
- Capable of operating in high current strings
