LP3943SW-LINUX: LP3943: synchronize the periodic blinking of all LEDs

Kay Teng

Part Number: LP3943SW-LINUX
Other Parts Discussed in Thread: LP3943, LP5012

Hi all,

We control the 10 LEDs with LP3943.
Our customer wants to set all LEDs to blink periodically at the same time.
But, if set for each LED, all the LEDs may not blink at the same time, but may blink separately.
Is it possible to synchronize the periodic blinking of all LEDs?
Please let me know if there is a way to synchronize.

Thanks.

Hi Kay,

Due to the separate registers of 10 LEDs and lack of enable pin, it is hard for us to synchronize the periodic blinking of all LEDs.

Instead of LP3943, LP5012 is a better choice. LP5012 is a 12 channels LED driver with flexible dimming function and it can control all LED blinking at the same time.
