John Griffith

Part Number: DRV8353

Hello,

My customer is looking at the DRV835x family and is unable to find any information in teh datasheet about the bandwidth of the current sense amp. Can you share the bandwidth?

Hi Akshay,

Customer said they run their motor current loop at 32KHz, with PWM frequency updated in 64KHz. Is this possible with our devices?

Hey John,

Could you elaborate on what you meant by motor current loop? Our device can handle up to 200kHz fPWM frequency.

Akshay
