Hi,
I am trying to drive bldc motor with drv8307 ic on my own board. When i drive motor with DRV8307EVM board, the motor draws its normal current 1.45A. But when i drive motor with my own board the motor draws 2.5A. ( The capacitors and resistors are 0402 smd package on my board, so i am not sure this affects the result). My schematic represantation is below.
Any suggestions ??
Hi,
I am trying to drive my bldc motor with my own drv8307 board and DRV8307 EVM board. My bldc motor normal current is 1.45 A ( and it draws this normal current with DRV8307EVM board and there is no problem with DRV8307EVM board) , but with my own board it draws 2.5A. I have used 0402 package capacitors and resistors, my schematic representation is below. The pwm frequency is 20kHz.
