Part Number: TPS51604

Dear all.

Would you please teach me about DRVH and DRVL output current of TPS51604?

Regards,
PAN-M

    Hi PAN-M, 

    The sourcing and sink resistance of gate drive is available in spec table on datasheet page 4. 

    The sourcing and sink current can be calculated as (VDD-Vgate)/Rgate

    For example, the typical sourcing resistance of DRVL is 1.5ohm, the VDD voltage is 5V, the initial gate voltage is 0V. Then the initial sourcing current is (5V-0V)/1.5ohm=3.33A.

    With gate voltage increases, the sourcing current decrease. 

    Thanks
