Hi,

I received following question from my customer.

The datasheet says that RTMIN is 10kΩ such as following.

Could you tell me the maximum RTMIN value for our reference?

This information is necessary to solve the problem which is occurred by current product.

Best Regards,

Hello Kuramochi-san

The maximum value we recommend for RTMIN is 135kOhms - as shown in the graph. The device would probably work with RTMIN greater than this but we would not guarantee correct operation.
