I currently have a PCA9685 LED driver IC, which offers 16 channels of individual PWM control but with only 10mA source capability. I would like to control 16 12V outputs, each at up to 200mA (for activation of coil-based relays). Following on from this post, have there been any major updates in the industry regarding multi-channel N channel MOSFETs? I've searched through all the usual websites and haven't come across anything obvious. I'm somewhat space limited, so won't be able to manage 16 single or 8 dual-channel MOSFETs, and would rather look at 8- and/or 16-channel options (if they exist) before I look to use quad channel ICs.
If 8- and 16-channel MOSFETs aren't available, is there another option I could consider? The ULN2803A seems like a good option, but I'm not sure how I'd maintain a 12V output given the additional voltage drop?
