UAA2016P

The UAA2016P from On Semiconductor is a specialized power controller designed to drive triacs using the Zero Voltage technique. This method enables RFI-free power regulation, making it ideal for resistive loads in electrical heating systems such as panel heaters or irons.

This device operates directly on the AC power line and includes a built-in digital sawtooth waveform for proportional temperature regulation within a ±1°C band. Additional features include a programmable temperature reduction function for energy savings and a sensor failsafe that inhibits output pulses if the sensor connection is broken. The hysteresis can be adjusted up to 5°C, and the component count is kept low with minimal external parts.

The UAA2016P is available in an 8-PDIP package and is suitable for through-hole mounting. It operates within a temperature range of -20°C to 85°C. The RoHS status is listed as RoHS3 Compliant, MSL is 1, and REACH is Unaffected, though these compliance details are noted as low confidence from the existing database.

Key electrical characteristics include a typical supply current of 15 mA, a maximum non-repetitive supply current of 200 mA, and a maximum output current of 150 mA. The device also supports adjustable hysteresis and preset temperature applications like defrost.
