Regarding the L6452, how did you connect the Vboost pins, i.e. pin 87, 88 and pin 89. The datasheet does not give any clue. regards

For the driver I'll give TLC59213 a go, if there is problem, after all this chip was not designed for the printhead job, I'll use the L6452.

This board has similar MCU as you are using (ARM cortex). It's on the other side of the PCB. The trouble was with all the parts on this tiny board (22mmx92mm) the board was barely routed, even I had to break a few of my good practice design rules to get this PCB done. I should be able to get the PCB...

That's cool! Also, meeting my Smart Printhead Driver 45 (SPD45) ...

I'll try to get the PCB done this week.

The 10.8~13.2V for the address voltage is a bit annoying, which means it may need a separate power while the primitives can go from 5V to 13.2V. The minimum 10.8V for the address also implies lower than this voltage the gate may not be fully open and excessive voltage drop over the gate FET can burn...

also does the address line have to be 12V, If 5V can open the gate, the driving would be a lot easier.

that's great! also thanks for the information regarding the firing order and the nozzle offsets. It also makes the CD4017 scanning very challenging if you want the head able to do dual direction printing, i.e. reverse the scanning order.

also in order to ease the PCB routing, the scanning order is not A1, A2, A3 ..., but something like A1, A5, A2 ... I think as long as all 22 addresses are scanned it would complete the firing. Please let me know if I missed anything.

thanks. I'm currently building a driver board with, - LVDS serial interface for long distance connection; - on board buffer and trigger and sync; - on board DC-DC converter to control the head voltage; - ESD protection; - temperature control; - nozzle diagnose Is there anything I should be careful w...

I'm right in thinking this pad footprint is the "bottom view", i.e. as the following picture,



Many thanks
