PT8A3252WE

Power Management - Specialized Overview

The PT8A3252WE is a mixed-signal CMOS LSI chip designed as a heating controller with multi-LED indicators. It supports dual voltage operations for 120V and 240V power lines at 50/60Hz frequencies, automatically detecting the supply parameters. The device features five heating temperature steps, typically ranging from 100°C to 180°C, controlled via an external NTC sensor. It includes auto power-off functionality after one hour and provides pulse triggering for high-current SCRs or TRIACs up to 15mA. The component operates within a supply voltage range of 4V to 6V and dissipates up to 500mW.
