| Modern equivalent of a IXDD414PI H bridge driver IC?? |
| (1/2) > >> |
| Chris Wilson:
Can anyone suggest a currently available equivalent of the obsolete IXDD414PI H Bridge driver IC chip please? Thanks. Whilst 8 pin DIP format is the preferred other formats could be pressed into use. Spec of the IXDD414PI is at: http://ixapps.ixys.com/datasheet/99061.pdf |

IXDD614 is still alive and well. Hmm, it was half a decade ago I designed in one of those, can't be too bad. Tim |

There are tons of gate driver ICs in the wild. https://eu.mouser.com/Semiconductors/Integrated-Circuits-ICs/Power-Management-ICs/Gate-Drivers/_/N-6j773?P=1z0jzfz&Ns=Pricing%7c0 Look through catalog and see what suits your requirements. |
| SiliconWizard:
There's a lot of gate drivers, but at 35V/14A max, not that many... so that would really depend on your requirements. Do you really need those specs? Ixys has been bought by Littelfuse and their current references are there: http://www.ixysic.com/Products/IGBT-MOSFETDvr.htm Edit: after reading your post again, you're mentioning " H Bridge driver IC " whereas the IC you mention is a low-side gate driver only, so I'm now thinking that what you need may not be what we think. Were you actually using this IC as a gate driver or directly as an half-H bridge (I guess it could be used that way, although it would probably be less than ideal as I didn't see any handling of dead-time)? |
| Chris Wilson:
Thanks for the replies. It seems there's a 614 version that may be suitably equivalent. It's a IXDD614PI I am merely thinking of building a directly rectified 240V AC mains powered low frequency (136kHz) RF amplifier from a schematic devised by someone who appears to successfully use the design himself. I am far from technically astute enough to critique it or change it I am afraid! Here's the circuit in question, in another thread on this forum it has come in for some criticism, but as I say, I am not qualified to comment constructively nor make changes... :( |
