Part Number:drv8305
Hi. I am driving mosfets with 80nC total gate charge using DRV8305 in FOC ESC. PWM frequency is 45kHz. I have several questions.
1. As I understand I need 2-3 Amp peak gate drive current to switch my MOSFETs efficiently, but DRV8305 gives max 1 Amp. In my case, to what negative effect this may lead? Do I need to change to MOSFETs with lower gate charge?
2. Do I need to change HS and LS Gate Drive Control settings in registers to max? Now my ESC drives my motor very well with standart settings, which are 50-60 mA.
Some explanation would really help, there is not much about this topic in documentation.
Thank you,
Roman
