Hello team,
I'd like to estimate the operating current of UCD3138A. Could you please check my understanding as below?
From the previous thread, I understand the total operating current when all DPWMs are unloaded is I_33, which is max 105mA according to DS.
I wonder how I can estimate the operating current with DPWMs loaded. Can the equation below be effectively/roughly used for estimating the current with loads?
--> I_loads = fsw x Qd (fsw : switching frequency of each DPWM channel, Qd : capacitance of driver connected to each DPWM channel)
If so, the total current would be I_33 plus I_loads. Is it correct?
Thank you so much!
