This thread was from a few months ago but wanted to add something. First those chips are pretty cool due to their size so i'll have to try soem at some point.
Secondly people keep saying the HV5530 needs 12V logic. I've run these at 3.3V and all seems to be good. I based this on the data sheet where it said Supply Voltage, VDD –0.5V to +15V then Logic Input Levels –0.5V to VDD+0.5V I interpreted that as plus or minus a half volt to the 3.3V it's running at. Have I got that wrong and the fact it's "working" is a bit of a fluke ? :) On Saturday, October 28, 2017 at 10:33:45 AM UTC-7, SWISSNIXIE - Jonathan F. wrote: > > > Hi folks, > > We all know the PLCC Style HV-Drivers from Microchip, for example HV5530. > All of them require a +12V Data Signal according to datasheet, but yet the > run in some circuits with even 5V data signals.. > > > While browsing microchips website i found HV5523/HV5623. > http://ww1.microchip.com/downloads/en/DeviceDoc/hv5523.pdf > > Those are fast 16Mhz registers with 5V logic data and can switch up to > 220V@100mA per Channel and come in a very small QFN package.
