LM5041: dead time adjust

Part Number: LM5041

Hi Team,

I understood dead time of PUSH, PULL pin can be adjusted by RSET.
Is there any method to adjust dead time for HD, LD pin?

Best Regards,

    Hi Yaita-san,

    There is no mention of adjustment for the dead-time between the HD and LD pins in the datahseet.

    The timing can be adjusted by adjusting the value of an external resistor in series with the gate of the mosfet to delay the turn-on of the mosfet. A diode can be placed in parallel with the series resistor to bypass the resistor during turn-off to allow the mosfet gate to be discharged by the LM5041 gate drive.

    Regards
