STMicroelectronics Introduces Fault Management Chip for Multiple LED Lights

STMicroelectronics (ST) has introduced a new fault management chip that enables the reliability and durability of key lighting LEDs such as lights, street lights and emergency lights to be even better.

The new product LBP01 is used for illuminators consisting of multiple LED strings. In the absence of LBP01, failure of one LED can cause all strings to go out, affecting the total output light of the entire system, forcing the owner to replace the lights in advance. The lighting system using LBP01 allows the current to bypass the faulty LED light and continue to supply power to the remaining normal LED lights, ensuring that the brightness of the lighting is close to the maximum, which improves the performance and safety of the lighting system and helps lighting companies such as Municipal government companies can save on maintenance costs, and the total cost of replacing a street light can be as high as $700.

Compared with similar products on the market, LBP01 has many advantages. Competing products typically only bypass one LED light, and the LBP01 bypasses two LED lights. This flexibility allows designers to reduce material costs. In addition, the product also provides surge protection to prevent power surges from burning LED lights.

According to market forecasts, as of 2015, sales of LED-based advertising screens and lighting markets (including headlights and streetlights) will exceed $5 billion. LBP01 also extends the life of LCD backlights in a variety of devices. To maximize onboard design opportunities, ST offers two different packages of LBP01, allowing designers to choose a 3.95 x 5.6 mm SMB package to directly replace competing products or a more compact solution in a 3 x 3.05 mm SOT23-5 package. Program.
