PT8A3246 Overview
The PT8A3240/1/2/3/14/5/6/7 is a mixed signal CMOS LSI chip designed for the automatic controller of heat with external NTC (Negative Temperature ponent). NTC open protection is implemented for device safety. When NTC is open, it will cut off GATE output to disable heating, and the LED1 will flash at 1/8 CLK.
