I am having 100% failure rate trying to get this high side driver to operate. The failure happens as soon as the 5v logic signal is turned on. I have had straight shorts from VDD to GND, and I have had burnt smoking chips. I am clearly doing something incorrectly.
Following the schematic i made:
The driver datasheet is: Fan7371
Diode data sheet: c3d04065A
Power supplies used:
tektronix PWS2323 DC power Supply 0-32V, 3A
IGBT data sheet: IXXH110N65C4
last circuit the 10ohm Rboot (replaced with 100 ohm in picture) burnt out and then the driver when I was noticing that the capacitors were discharging when VDD was turned off. Pretty sure this should not happen.
The circuit will eventually be run at much higher voltage which is why the overkill on some of the parts.
The pins are correct on the IGBT. orange wire going to 1 (G) and blue going to 3 (S)
In response to the answer:
Similar to this typical setup from the data sheet.
If i add a diode from source to ground would that provide a better result? It was my thinking that CB was able to find the off time charge path through the load ground. when i turn the first supply on it has no trouble charging to 15 volts, but CB does discharge immediately if i turn it off as well.
