Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Part Number: LP5862 Other Parts Discussed in Thread: LP5861 Assuming we would like to use the LP5862 to only drive up to 16 LEDs and not in the 2x matrix arrangement, is it possible to connect the LEDs anodes directly to VLED instead of SW0, bypassing…
Part Number: LP55231 Other Parts Discussed in Thread: LP5813 , LP5861 , LP5018 Hello,
I am using two LP55231 to control 6 RGB LEDs.
When I turn on all LEDs with max brightness, both ICs heat up to more than 80 degrees celsius. I stopped the testing as…
Hi,
Yes, the sub address could not use to control a subgroup of output pins, it is used to control a group of devices together.
Which means you can set a same sub address for multi-devices and control them together with SUBx = 1 . And you can set SUBx …
Hi,
If you need more channels, please consider LP586x family, it can handle 18(LP5861) - 198(LP5860) LEDs. For your application, I think LP5862, which can drive 2*18 LEDs, is also suitable for you.
Thanks!
Hi Danilo，
Nice to hear you.
BLANK pin is used to force all outputs off，if they only want to turn on/off different outputs separately，this pin may not useful for them.
Because this device is based on shift register，so all the outputs need to be configured…
Part Number: TLC5916 Other Parts Discussed in Thread: LP5861 Customer is looking for a 15ch brightness control for LED driver. the PWM dimming is 1KHz.
Is there device that is able to support individual current control per channel? It means that the each…
Hi Pragash,
25mA is the peak current limitation. If you want larger current ability, you could parallel multiple output channels or refer to other devices like LP5861 or TLC59116.
Best Regards,
Aaron
Part Number: LP5018 Other Parts Discussed in Thread: LP5861 I understand that LP5018 is a RGB led driver, with brightness bank control for 3 led outputs. As per datasheet, there are only below registers available for controlling led brightness through…
Hi Jonathan,
1. TLC59291 controls LED current without PWM-ing the output. Actually, it is analog dimming.
2. TLC59291 is a device with 7-bit global brightness control. That is to say, the current outputs of all available channels are adjusted to the same…
