Hello,
I am designing a BLDC motor driver for an actuator and decided to use OnSemi LV8907 as a pre-driver IC. It has a voltage range from 5.5V to 20V. My input voltage would be 24V nominal but the PCB will be tested on a 36V for 1hour and 48V for 15min. The block diagram of the IC is below.
My questions are;
1) Is it possible to supply this IC with a buck converter and the motor is connected Vbat? Also, can I supply both IC and motor with a buck converter?
2) Could the switching regulator create some EMC problems?
3) Does the regulator have any positive or negative effects for ISO 7637-2 transient voltage pulses?
Or will you advise me to choose a more proper pre-driver with a proper voltage range?
Thank you!
