Texas Instruments LP5899/LP5899-Q1 LED Drivers
Texas Instruments LP5899/LP5899-Q1 LED Drivers are SPI-compatible devices with an internal oscillator to generate the continuous clock required by the LP589x/LP589x-Q1 family. These LED drivers incorporate reporting faults in the LP589x/LP589x-Q1 daisy chain and LP5899/LP5899-Q1 internal. The LP5899/LP5899-Q1 devices can drive any number of cascaded LED drivers of the LP589x/LP589x-Q1 family, and the LED driver limits the maximum number of cascaded devices. These LED drivers operate at -40°C to 125°C temperature range. The LP5899/LP5899-Q1 drivers are ideal for SPI-compatible connectivity for LP5891/LP5891-Q1 and LP5892/LP5892-Q1 devices. The Texas Instruments LP5899-Q1 devices are AEC-Q100 qualified for automotive applications.
