Part Number:UCC27211
Hi for everyone who is reading this,
For a project I am experimenting with the UCC27211 high and low side mosfet driver. I want to make a "power" amplifier using the stated driver in combination with a n channel trench mosfet (SQP90142E). But it seems that I can't get the driver working properly. As a reference I used the "UCC27211 transient analysis" that is available for Tina-TI (see picture below). I adjusted the capacitor load (CloadHO & CloadLO) with a rough estimation of the N channel mosfet I intend to going to use.
After building the circuit I measured with a scope the HO and LO outputs. The graph is in my opinion correct (minus the huge transients on the flanks, but that is probably due to that I use a bread board (A)). 
Only when I connect the N channel mosfets gates to the LO and HO output (without connecting to mosfet any further) the HO output goes to 0 and will not recover anymore even when it is not connected anymore. And when I try to build the circuit stated in the datasheet, using the circuit with only one UCC27211. The mosfets will conduct straight away doesnt matter what timing the HI and/or LI has.
Does someone already experienced this or knows a solution, I will be very glad to hear it.
Kind regards,
Remco
