Recently, Accumulation Technology released the new high-brightness, multi-stage dimming constant current LED driver chip MBI1812. This chip provides two constant current output channels, using PrecisionDrive and All-Ways-On technology developed by the accumulation, which makes the current between different output channels more accurate, and can set high current of 40mA to 360mA per channel by two external resistors. Value to control the brightness of the LED.
The MBI1812 is the new driver chip for the All-Ways-OnTM lighting solution family. Its main feature is the ability to input pulse width modulation (PWM) signals to control the brightness of the LED illumination, ranging from 0% to 100%. In addition, by the control pin, the current adjustment can be further set by 25% and 50%, and the hysteresis of the input voltage of 200mV is designed between the multi-stage dimming switching points, which not only realizes a wide brightness adjustment range, but also enables dimming. Switching is more flexible, smooth, and avoids interference.
High-brightness LED lighting pays the most attention to heat dissipation. Therefore, the MBI1812 is packaged in SOP8 with built-in temperature sensor and overheat protection, and heat sink for heat dissipation. When the temperature is too high, the overheat protection function turns off the current and prevents the temperature of the driver from being too high. Once the temperature returns to 130 ° C, the output current will be turned back on to achieve safe processing of high output current, making the LEDs use longer, stable and reliable.
The All-Ways-OnTM series is an illumination driver chip for different output channels and different current values. The current range is from 60mA to 360mA. The external resistors can be used to adjust the current output value. The product range includes flash, automotive lighting, general lighting and decorative lighting. Wait.
To use these connectors, the ribbon cable is inserted into the Ribbon Connector and the connector is then plugged into the Ribbon Connector on the circuit board. The connectors are designed to provide a secure and reliable connection that can withstand repeated insertions and removals.
Overall, the 2.54mm Ribbon Connectors are an essential component in many electronic devices that require a reliable and secure connection between the ribbon cable and the circuit board.
