LM5104: Additional deadtime
Part Number:
LM5104
Hi, Can the value of RT be safely increased beyond 100k for additional deadtime? I would like to achieve an addition ~100ns of deadtime on top of what is achieved with RT = 100k. Kind Regards, Andrew

RE: LM5104: Wrong signal when connect to mosfet
Hello, Thank you for the more detailed waveforms and schematic. It appears the HO output and timing seeing the LO rising to some lower level seems correct. The LO output seems like it is being limited to a low level by something in the circuit. Can...

TPS2834: Low side of MOSFET driver not operating at all when in synchronous mode and using in full bridge configuration. External modification had to be performed in order to get this working.
TI Thinks Resolved
Part Number: TPS2834 Hello, When using two TPS2834 MOSFET drivers (and MOSFETS) in a full bridge configuration (as seen in the schematic below) and in synchronous mode (by holding the SYNC pin high), the low side driver signal LOWDR (going into the...
