Other Parts Discussed in Thread: DRV8243-Q1, , LM74610-Q1
We have 2 questions related to DRV8243-Q1 and its EVM.
- Customer found out that there is a periodical voltage drop when using DRV8243H-Q1EVM:
Frequency is 2.5kHz and the device is in a full-bridge operation. VM = 18V supplied from a stable power supply.
Every 1.284 sec, there is a slight voltage drop as seen in the above figure.
What would be the reason? Can we fix this?
- When VM pin = 0V but nFAULT pin pulled up with 10kOhm, is it ok with this condition which current flows?
