DIODES Incorporated Power Management - Specialized PT8A3294BPE

The PT8A3294BPE is a mixed signal CMOS LSI chip designed for heating control applications. It operates on dual voltage systems (120V and 240V) and features automatic temperature control using an external NTC (Negative Temperature Coefficient) thermistor. The device includes NTC open protection for enhanced safety and employs a proportional control algorithm to manage heating effectively. This heating controller supports a pulse trigger for high current SCR/TRIAC outputs, with a maximum output current of 15mA. It also incorporates a timer function that automatically turns off the heating after a specified duration. The PT8A3294BPE is available in a low-cost 8-pin DIP or SOIC package, making it suitable for various applications, including hair curlers and straighteners. The device operates within a temperature range of -20¬8C to 85¬8C and has a storage temperature range of -65¬8C to 150¬8C.
