TLC5927-Q1 汽车类 16 位恒流下沉式 LED 驱动器
TLC5927-Q1 描述
The TLC5926/TLC5927 is designed for LED displays and LED lighting applications with open-load, shorted-load, and overtemperature detection, and constant-current control. The TLC5926/TLC5927 contains a 16-bit shift register and data latches, which convert serial input data into parallel output format. At the TLC5926/TLC5927 output stage, 16 regulated-current ports provide uniform and constant current for driving LEDs within a wide range of VF (Forward Voltage) variations. Used in systems designed for LED display applications (e.g., LED panels), TLC5926/TLC5927 provides great flexibility and device performance. Users can adjust the output current from 5 mA to 120 mA through an external resistor, Rext, which gives flexibility in controlling the light intensity of LEDs.
