USA - California Micro Devices (http://) announced the latest product in the LuxGuard10 family of turnkey solutions for ESD (electrostatic discharge) protection and thermal management for high power, high brightness light emitting diode (HBLED) lighting The new CM1771 is the industry's first ESD protection solution for HBLED applications to feature a 100 volt breakdown voltage ESD rating.
The enhanced level of ESD protection is a requirement for a growing segment of high power HBLED lighting applications that feature high output power, high efficacy levels reaching over 120 lumens per watt or those utilizing multiple HBLEDs driven in a serial arrangement.
Delivering ESD protection at high operating voltages poses the new challenge of dissipating a higher level of power during an ESD strike, and also in maintaining acceptably low dynamic clamp voltages. A silicon-based, side mount protection solution with a back-to-back electrical Configuration, the LuxGuard CM1771 provides robust, symmetrical ESD protection and features a very small, cost effective die that can easily be integrated into a broad range of HBLED lamp modules.
Satisfies Trends in HBLED Market
The market for high power, HB LEDs has expanded beyond traditional market segments such as status and alphanumeric display markets into a wider range of lighting applications including display backlighting, automotive, signs, and residential and commercial lighting.
To meet this growing market, products are now being designed using serial strings of HBLEDs, sometimes of up to 30 to 40 devices to increase the brightness levels. Existing side mount ESD protection solutions for HBLED offer breakdown voltage specifications that are limited to about 50 volts , making them inappropriate as a single chip solution for these higher power and multiple HBLED applications.
CM1771 Product Specifications:
- Back-to-back zener diode configuration for bi-directional ESD protection
- Safely dissipates ESD strikes of at least 6 kV, Human Body Model (HBM)
- 100 volt breakdown voltage rating (typical)
- Top pad composition: Gold
- Compact flip chip package
- CM1771 Applications
- LED Lighting
- Modules
- Interface circuits
