Description
 Dual Voltage (120V/240V) operations
 Auto temperature control with NTC
 NTC open protection
 Multi mode LED indicator
 Proportional control
 Pulse trigger for high current SCR/TRIAC (up to 15mA)
 Internal Zener
 Auto Heating off after heating timer timeout
 Low cost 8-Pin DIP and SOIC package The PT8A3280/1/2/3/4/5/6/7 is a mixed signal CMOS LSI chip designed as heating controller with help of external NTC (Negative Temperature Component). NTC open protection is implemented for device safety. This device can be used in both 120V and 240V power line supplier, as it will.
