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¬8C, 145¬8C, 160¬8C, 175¬8C, and 190¬8C, with the capability to adjust the temperature range from 100¬8C to 250¬8C 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¬8C. 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.
