Pericom Semiconductor Corp. PMIC - PMIC - Power Management - Specialized - PT8A3287PE PT8A3287PE

The PT8A3287PE is a heating controller designed for dual voltage operation at 120V and 240V. It features auto temperature control using an external NTC (Negative Temperature Coefficient) thermistor, which includes NTC open protection for enhanced safety. The device employs a proportional control algorithm to adjust heating power based on the input voltage, preventing damage to heating appliances and reducing heating time. This controller is packaged in a low-cost 8-pin DIP format and is suitable for applications such as hair curlers and straighteners. It includes a multi-mode LED indicator and supports pulse triggering for high current SCR/TRIAC outputs, with a maximum output current of 15mA. The PT8A3287PE operates within a temperature range of -20¬8C to 85¬8C and has a power dissipation capability of 500mW. Engineers considering this product should note its compatibility with various heating applications and its built-in safety features, making it a practical choice for heating control solutions.
