I'm looking to build a little project with four alphanumeric displays from kingbright:
Here's my challenge: half of the segments run at less current in each display. The displays also have a common-cathode for all 16 segments (decimal not necessary for my project).
So I was thinking to use something like two MAX7219s or two MBI5026s, one for the segments that want 30mA, the other for the ones that want 60mA.
After a lot of research, my head is spinning and I'm concerned I can't make it work because of the mix of common cathode, as well as well as the heterogeneousness of currents that are needed within each character.
Any IC suggestions anyone could offer would be very appreciated. Not afraid of datasheets
Thanks for your thoughts and suggestions in advance.
edit the link was to the common-anode product, not the common-cathode. Here is the datasheet for the correct part:
