DRV8904-Q1: PWM generator frequency > 2kHz

Part Number: DRV8904-Q1
Other Parts Discussed in Thread: DRV8874-Q1, DRV8876-Q1, DRV8876

Hello,

My customer is interested in DRV8904-Q1, but they'd like to have >2kHz from the PWM generator.  If I understand correctly, DRV89xx-Q1 devices can output PWM up to 2kHz by configuring the register.  Do you have a device which can output >2kHz?  Or do you have roadmap of developing such devices?

Best Regards,

Yoshikazu Kawasaki

    Kawasaki-san,

    Can you tell me more about the application?  How many motors to drive?  Bidirectional or uni-directional brushed?  We have other devices with PWM interface like DRV8876-Q1, DRV8874-Q1.

    Regards,

    Hello Ryan-san,

    Thank you very much for your reply.  It seems the background of the question is to know if there are devices which can work with higher frequencies to think about the prevention from the squeal of the coil.  They understand DRV8876/4-Q1 support PWM input up to 100kHz.

    Best Regards,
