Hi Sir,

I would like to survey fan controller with I2C watchdog timer, please check the requirement in below.

Customer can accept multiple solutions if single one can not achieve.

1. 12 PWM channel

2. 12 TACH channel

3. I2C watchdog timer, once timer time out, PWM output 100%

Thanks a lot.

Regards,

Allen

    Hi Allen,

    Thank you for posting to the Sensing forum.

    Although we don't have a device up to 12 channels, I would suggest looking at the LM96000 datasheet to check if this will work for the customer's application. The LM96000 has 3 available addresses, which can provide up to 9 PWM outputs and 12 TACH outputs.

    Best regards,

    Nicole
