Is there any particular sequence of giving the THSD voltage? We initially had connected it to high voltage directly without giving the pull up resistor. The chip works fine when VDDM is given first and VDDP (also DVDD) given second. But it draws infinite current when VDDP is connected first and VDDM is given afterwards. We removed THSD pin and manually connected it to positive supply after giving the power supplies and the IC works fine irrespective of the order of the supplies. How is this possible?
