TPS3825: TPS3825-33 reset at -30 deg C~40 Deg C

Part Number: TPS3825

Tool/software:

Dear SirMadam,

My end customer is using TPS3825-33DBVT for voltage monitor (meter function), They are doing reliability test on thier end product and when temperature reach -30 degc, they noticed the unit keep reseting the MCU. 

The picture on the right is their connection diagram which the unit suppose to generate reset when VDD fall below 2.93V. I saw their circuit has some extra resistors in front of /MR pin, I would like to know will this causing this failure issue. 

According to application section of datasheet, the connection diagram is as follow:

Hope to get some advise. thx

Best Regards,
