Overview
The PT8A2704WE is a mixed-signal CMOS LSI heating controller manufactured by Diodes Incorporated. It operates on a single supply voltage ranging from 4V to 5.5V, with a nominal voltage of 4.5V. The device supports dual voltage operations for both 120V and 240V power lines, automatically adjusting heating power to prevent appliance damage. It features an internal proportional control algorithm and pulse trigger for high-current SCRs. The component includes auto-heating off functionality after a timer timeout and provides NTC open protection for safety. It is housed in an 8-pin SOIC package.
Feature Summary
- Dual Voltage (120V/240V) operations
- Auto temperature control with NTC
- NTC open protection
- Multi mode LED indicator
Applications
- Hair curlers
- Hair straighteners
- Heating appliances requiring proportional control
Procurement Notes
Verify the specific suffix 'WE' corresponds to the SOIC-8 package variant when ordering. Confirm RoHS compliance status through official datasheets or manufacturer declarations prior to procurement. Ensure the selected component matches the required operating temperature range for the target application environment.
Selection Notes
Select this component for applications requiring automatic adjustment between 120V and 240V mains voltages. It is suitable for designs needing integrated NTC temperature sensing and proportional heating control without external complex circuitry. Consider the SOIC-8 package constraints for PCB layout and thermal management requirements.
Part Context
This part belongs to the PT8A327x series of heating controllers from Diodes Incorporated. The series shares common features such as dual voltage support and NTC protection, with variations primarily in packaging or minor functional configurations across different suffixes like PT8A3270 through PT8A3277.
Replacement Considerations
Cross-reference with other members of the PT8A327x series, such as PT8A3270WE or PT8A3271WE, if pin compatibility and functional equivalence are confirmed by the manufacturer's documentation.
