Hi,
We need to design a printer head driver with 64 output channels in which each channel should be able to source max of 400mA, 40V. Our plan is to implement digital logic like shift register and Latch in FPGA and design 64 output channels which require a lot of Mosfet. Right now, we are looking for chip solution for 64 output channels. Attached is the single output channel circuit which provides 200-400mA, VH -40V, the same has to reproduce for other 63 output channel. Using individual MOSFET is not the right solution as it will increase the board size. As of now, I have found that MAX14912/MAX14913 which supports 8-channels and TLE94110EL which support 10-channels. But, the big concern with these chips is their size as I need to put 8 drivers to make 64 output channels. So, if anyone has come across a driver that will suit for our application, please suggest...
Thanks,
Muthu
