HBL1025: LED Shunt
The HBL1015/25 Series are electronic shunts which provide a
current bypass in the case of LEDs going into open circuit. LEDs are by
nature quite fragile when subjected to transients and surge conditions.
There are also many cases where high reliability of the LED lighting
must be maintained such as in headlights, lighthouses, bridges, aircraft,
runways and so forth. In these cases the low cost addition of the HBL
device will provide full assurance that an entire string of LEDs will not
extinguish should one LED fail open. The HBL device is also
applicable to other loads where circuit continuity is required. The
devices can be used with currents from 140 to 500 mA.
Features- A Bidirectional Device
- Automatically Resets Itself if the LED Heals Itself or is Replaced
- ON−State Voltage Typically 1.8 V
- OFF−State Current less than 0.5 µA
- These are Pb−Free Devices
|
Applications- LEDs where Preventive Maintenance is Impractical
- LED Headlights
- LEDs with High Reliability Requirements
- Crowbar Protection for Open Circuit Conditions
- Overvoltage Protection for Sensitive Circuits
