I am currently designing a new product using 2 pieces of the attached display.
I finished with the PCB design but unfortunately I realised that the final price is out of range. I used 1 pieace of the TD62783F (High side driver to control the columns) and 2 pieaces of the ULN2803A (to control the rows). There are also some other signals that have to do with other functions, that's why I used the ATMega64.
Is there any other solution to control the specific product dots (30mA (max) constant current and 100mA (max) peak current per dot). What would you do ?
The product power supply have to be in the range of 8 up to 35Vdc and the current consumption is less than 100mA. Do you have any opinion about the regulator (5V) ?
