Hi TI-team
I would like to use lm74700-q1 as an ideal diode.
Is I(GATE) used when calculating turn ON and turn OFF times ?
Please tell me how to calculate in that case.
I(VCAP) (300uA) is used to calculate T(DRV_EN).
Is there a difference between T(DRV_EN) and turn-on time?
My specifications are as follows.
VinMAX=50V
Iout=50A, MAX=100A
The MOSFETs selected from 20mV/50A≦RDS(ON)≦50mV/50A=0.4mΩ≦RDS(ON)≦1mΩ are two IAUC120N06S5L011 used in parallel.
Ciss :8770pF
C(VCAP):8770pF×2×10=175.4nF
Calculating from the formula below, T(DRV_EN) will be approximately 3.9ms.
Best Regards,
Koji Hayashi
