Other Parts Discussed in Thread: DRV8876, DRV8874EVM

We have planned to use the KHLVA-101-5-P part in one of our projects

Do you have any controller to drive this device?

For your reference below i shared the link for KHLVA-101-5-P part

Requesting you to helps us on this.

Hello,

I think any of these devices would work as they are basically h-bridges. Depends on your current and voltage needs.

Helo Ryan,

sorry for the delay,

will use the heater in medical (lab) .

here by I attached the driver requirement .

1)Drivers shall be developed to provide PWM output at 24V DC (~4W) to heater film On PID constants is defined by the end user.

2) driver should support on software control to alter P, I, and D constants and set points

requesting you to helps us on this

Thanks,

Hello,

We don't have anything will integrated PID control. This would need to be done in a companion MCU chip to our driver.

Dear Ryan,

Can you suggest a MCU which will supports to our requirement

Thanks,

Pooja,

Please check the DRV8876 or DRV8874EVM, that MCU should be sufficient.

Dear Ryan,

Thanks for the support,
I have some query's on suggested part!

Suggested part application is different and our application is different,

Driver which needs to drive the Flexible polyamide driver
if iam wrong, please correct me.

Thanks,

Pooja,

It appears we have multiple threads going on this topic.

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1180102/required-ic-or-driver-to-drive-https-www-omega-com-en-us-industrial-heaters-surface-heaters-flexible-heaters-khra-khlva-kha-series-p-khlva-101-5-p-part

Let's keep the conversation going on the thread above please.

We are not experts in driving the load you are using. All I can recommend are standard H-bridges that can be used to control current. The loop would have to be closed outside of our chip and I can't help you with that. We have recommended devices and micro-controllers. That is the best we can do.

Regards,

Ryan
