  • Description

    The SL441C is a symmetrical burst control integrated circuit in an 8-pin DIL package. It is designed for AC power regulation by varying the number of mains cycles applied to the load in a fixed timing period. This makes it suitable for room temperature control applications, including panel heaters and fan heaters. It utilizes zero voltage switching to minimize radio frequency interference.

    Specifications and features

    - Balanced zero voltage point crossing detector, spike filter, and pulse generator for reliable triac triggering.

    - Period pulse generator and bistable arrangement for symmetrical burst control and elimination of 1/2 wave firing.

    - Ramp generator to modify internal reference voltage based on thermistor voltage, creating a proportional control system.

    - Comparison amplifier with inbuilt hysteresis to eliminate switching jitter and spike filter/sampling circuit for high immunity to spikes and coherent 50Hz/60Hz.

    - Automatic power removal in case of thermistor malfunction.

    - Supply voltage sensing circuit to inhibit firing pulses when the supply is inadequate, preventing stressing of the triac at switch-on.

    Application Scenarios

    - Room temperature control applications, such as panel heaters and fan heaters.

    Comparison

    Advantages

    - Allows for AC power regulation by varying the number of mains cycles, providing precise control for room temperature applications.

    - Utilizes zero voltage switching to minimize radio frequency interference.

    Disadvantages

    - None mentioned.
