Other Parts Discussed in Thread: UCC27282
Hello team,
I'm confused with I_DD and I_DDO.
From my most understading, I_DD is just a standby current when the driver is turned on, but no PWM input. And I_DDO is a operating current when the driver is turned on with PWM input, but no output load (no gate FET connected to HO and LO pins). Could you check if it's correct?
In addition, I'm trying to estimate total current consumption of this device. It's static operating current plus the current required to drive the MOSFET Qg. The later one can be calculated in Igd= Fsw x Qg, but I'm not sure about the former one (static operating current). Which one would be more proper for estimating current consumption, I_DD or I_DDO?
Thanks!
