Other Parts Discussed in Thread: DRA821
Hi Team,
I have a doubt in connecting USB0_VBUS pin of DRA821 processor. The below images refer to the information given in the TRM regarding USB0_VBUS signal. It is given as USB0_VBUS is a 3.3 analog input, my doubt is either we can give 3.3V directly or we should give 5V with voltage divider circuit? Also, in TRM it is mentioned as"5-V VBUS must be applied via an external resistive divider /3. For example, R1 = 20 kOhm and R2 = 10 kOhm", here they have mentioned as external resistive divider /3, what is meant by /3? Also, if use R1 as 20KOhm and R2 as 10KOhm, then the output voltage will not be 3.3V it will be 1.6V, whether is it okay or we should change the resistor values accordingly so that we get 3.3V as output.
With Regards,
