Other Parts Discussed in Thread: LP8864EVM
Hi,
I am using eight of the LP8864QDCPRQ1 in a design. I have a few questions:
- Since I have eight in a system (using an I2C mux to select each of them) and was wondering if you negate the EN pin, does that set all registers back to default?
- In a smaller application, I need to drive 91 LED's each with a 7Vf drop so I have 6 LED's per string. In this application I have four LP8864QDCPRQ1 in the system. Three will have 4 chains of 6 LEDs and the fourth will have 3 chains of 6 but then I only need 1 LED on the last chain. Can this be done? Do all four chains on the LP8864QDCPRQ1 need to have the same number of LED's and approximately the same total Vf?
- Finally, can someone review my schematic for these applications. It's the same schematic for all applications so it's one page for review.
Thanks!
John
