UCC28019A: UCC28019AD

Part Number: UCC28019A

For the brownout protection, it is recommended in the datasheet to use RVINS1 less than 10MOhm. As per my design, the input voltage minimum (VAC(on)) is150V, so RVINS1 comes around 14MOhm. I also considered 150 times input bias current. Does this high value of  RVINS1 creates any problem in the operation? is there any modifications to be done?
