TLC59731: Brightness control

Patrick Chen

Part Number: TLC59731
Other Parts Discussed in Thread: LP5562

Hello

1. Does TLC59731 support PWM control brightness for each 3 channel independently  ? 

2. TLC59731 use SDI/SDO control. How to send serial interface by processor? Could I2C or UART meet the protocol? 

3. TLC59731 has no internal FLASH. If customer use LED driver with FLASH that just send one command then LED will implement respiratory lighting function. Has any solution to suggest to customer? 

Thank you.

    Hi, Patrick,

    1. Yes, each channel has 8 bit PWM.
    2. TLC59731 is single wire interface, and you can refer to the timing diagram Figure 3 in datasheet. It doesn't support I2C/UART.
    3. We don't have LED driver that has flash but you can refer to LP5562 which has SRAM and instrustions that can help you to realize the effect.

    Please help to click "Resolve" if the problem is solved.

    Thanks.
    Regards,
