IES5431 electronic dual blanket controller IC with timing
IES5431 is a monolithic integrated circuit for duty cycle control designed specifically for electric blankets applications. It features independent control of two sections of the blanket from a single control IC, with the major part of the control function arising from the IES5431 built into the Master controller. Minimum external components are only needed in the Slave controller (refer to typical blanket circuit configuration) IES5431 also features a boost mode capability. Boost mode (10 mins) enables fast heat up time to warm up the bed. Inbuilt timer provides an automatic shut off that switch the heater control off after 10 hours of continuous operation. The boost and run times can be easily preset based on selection of external resistor and capacitor values. The LED indicator on the controller provides an indication to the user its current operating mode.
