DIODES Incorporated Power Management - Specialized PT8A3251PEX

The PT8A3251PEX is a mixed-signal CMOS chip designed for ceramic heating control applications. It features six preset temperature settings ranging from 150¬8C to 230¬8C, which can be adjusted using external series resistance. The device includes an internal timer that automatically stops heating after a specified duration, providing safety and efficiency. It also incorporates over-temperature protection to prevent overheating. The chip is available in lead-free DIP-16 and SOIC-16 packages, making it suitable for various PCB designs. It operates within a temperature range of -40¬8C to +85¬8C and supports a supply voltage of 4.0V to 5.5V. The PT8A3251PEX is particularly useful for applications requiring precise temperature control and quick recovery from heat loss.
