PT8A3517BPEX

Power Management - Specialized Overview

The PT8A3517BPEX is a smart iron controller manufactured by Diodes Incorporated, designed for use in electric iron applications. It operates within a supply voltage range of 4.5V to 5.5V and features a typical supply current of 400µA. The device supports an operating temperature range from -10°C to 85°C (TA). It utilizes an internal RC oscillator for sensor signal detection and offers accurate timing with an error margin of ±1%. The component is available in an 8-pin DIP package.

Power Management - Specialized Feature Summary

• Built-in RC oscillator enables precise sensor signal detection without external components
• On-chip shunt regulated power supply simplifies circuit design
• Selectable AC 60Hz/50Hz timer clock integration for accurate timing control
• High immunity against sensor vibration and sensitive movement detection capabilities

Power Management - Specialized Applications

• Smart iron controllers
• Electric iron systems with static horizontal position timeout
• Electric iron systems with static vertical position timeout

Power Management - Specialized Procurement Notes

Verify the part status as obsolete before procurement planning. Confirm compatibility with existing 4.5V-5.5V supply rails and DIP-8 footprint requirements. Review the official datasheet for recommended application circuits to ensure standby power dissipation remains below 1W. Validate that the selected variant matches the required AC timer clock frequency (50Hz or 60Hz) for your specific regional power standards.

Power Management - Specialized Selection Notes

Select this component when designing smart iron controllers requiring integrated timing and motion detection. Ensure the system voltage aligns with the 4.5V to 5.5V operating range. Consider the DIP-8 package constraint for PCB layout. Verify that the ±1% timing accuracy meets the thermal safety requirements for both horizontal and vertical iron positions. Check if buzzer support and LED indication features are necessary for the user interface design.

Power Management - Specialized Part Context

The PT8A3517BPEX belongs to the PT8A3514/15/16/17/18/19(A/B) series of smart iron controllers from Diodes Incorporated. This family shares common features such as built-in oscillators and shunt regulation but may differ in specific timing configurations or package types. The PT8A3517BPEX specifically targets applications requiring robust vibration immunity and accurate timeout functions for ironing appliances.

Power Management - Specialized Replacement Considerations

Public confirmed substitute part numbers are not provided in the available documentation. As the part status is listed as obsolete, alternative solutions must be evaluated based on functional equivalence, including supply voltage range, package type, and smart iron controller capabilities. Consult Diodes Incorporated for potential end-of-life replacement recommendations.
