  • LM5105 with 50ns dead time

    Other Parts Discussed in Thread: LM5102 , LM5105 Hi my customer wants to reach 50ns dead time on LM5105 / LM5102. our D/S says that deadtime can be adjusted from 100ns to 600ns which seems to tell that 50ns is not achievable BUT it also says that one can…

  • RE: LM5105 circuit troubleshooting

    I have been asked to look into this query. Could you please remove BOTH the Upper and Lower MOSFETs and re-measure the voltage on the HS pin of the driver wrt VSS ? Please also remove the 57.6K resistor between the motor node and VSS. Lets get the MOSFETs…

  • LM5105 Internal Bootstrap diode failure

    I am using LM5105SD - half bridge MOSFET controller in my design. The device was subjected to failure, observed by a low impedance path across Vdd and Vss power rail. It was also observed that IC which has failed, reads a low impedance of 12 ohms across…

  • LM5105: Duty-cycle-dependent power loss of Class-D power stage.

    Other Parts Discussed in Thread: LM5105 For a class-D power stage, I am using the LM5105 to drive Vishay power MOSFETs. The circuit is as simple as the setup shown in Figure 24 of the datasheet. During circuit qualification, I have been facing the following…

  • LM5101A vs LM5102/LM5105 bootstrap diode losses

    Other Parts Discussed in Thread: LM5105 , LM5102 In comparing the datasheets for the LM5100/LM5101x with the datasheets for the LM5102 and LM5105, there is roughly a factor of 3.5x increase in boot-strap diode dissipation for the 02 and 05 parts for similar…
