Accumulation of intelligent power saving mode LED driver chip MBI5037

LED driver chip international leader in the accumulation of science and technology recently published intelligent power-saving, with full screen silent error detection function of the 16 channel LED driver chip -MBI5037. This chip is specifically designed for a long time to open the LED traffic display and design, such as the LED speed limit chart, LED speed screen, highway LED message screen, etc.. Due to the use of the traffic screen, there will still be a display area in most of the time is not lit (as shown on the right), but at this time the driver does not have to be lit in the chip to operate, it will waste a lot of electricity. MBI5037 intelligent energy saving mode allows the driver chip is not lit, only less than 100uA power consumption, power efficiency of 99%, not only effectively extend the life of the chip, but also to allow LED to achieve energy saving realm.

MBI5037 provides mandatory sleep with 0 - Power power saving modes of two. In the application of LED traffic display, mandatory sleep mode is used in the absence of a car through, you can command LED forced sleep, when there is a car through, and then forced to wake up, wake up time is only 100us. With respect to the given command forced dormancy, as long as the output data is set as 0, 0 - Power driver automatically enter power-saving mode will be used in this chip, LED display part of the display area is in the closed state does not always need to light up. The two power saving modes have the same power saving efficiency of 99%, not only high efficiency, stable system, greatly reduced cost and easy to design, can help customers quickly into the traffic display applications.

Automatic error detection in traffic display applications for the necessary function, so that MBI5037 design is mandatory silent open / short circuit fault detection, let LED 700ns in a short time at low current 0.1mA to LED highlights and unlit point full screen fault detection, and the detection screen zero flicker, maintain the normal operation of the LED display the threshold voltage and output short-circuit detection and MBI5037 leakage current detection (threshold voltage) can be adjusted, according to different LED forward voltage changes.

MBI5037 can support the 3~80mA constant current output range, voltage up to 17V. With a patented Share-I-O technology, the MBI5037 pin can be fully compatible with the MBI5025/ MBI5026/ MBI5027/ 5028/ MBI5029 MBI.
