DIODES Incorporated Power Management - Specialized PT8A3254WEX

The PT8A3254WEX is a specialized power management integrated circuit designed for ceramic heating control applications. It features five internal temperature settings at 130°C, 145°C, 160°C, 175°C, and 190°C, with the capability to adjust the temperature range from 100°C to 250°C using external series resistance. The device can directly drive SCRs and detect heater temperature without the need for an additional temperature sensor. It includes over-temperature protection to enhance safety, ensuring the heater does not exceed 250°C. The PT8A3254WEX is available in lead-free DIP-16 and SOIC-16 packages, making it suitable for various PCB designs. This product is particularly applicable in high watt density alumina heaters and ceramic heating controllers.
