UM803RP

Supervisors Overview

The UM803RP is a 3-pin microprocessor reset circuit manufactured by Union Semiconductor. It functions as a supervisor to monitor power supply voltage and generate a reset signal for microprocessors. The device ensures system reliability by detecting under-voltage conditions and initiating a reset sequence when the supply drops below a specific threshold, maintaining stable operation in embedded systems.

Supervisors Feature Summary

• Provides automatic reset generation upon detection of power supply anomalies
• Ensures reliable microprocessor initialization during power-up sequences
• Supports stable system operation through continuous voltage monitoring

Supervisors Applications

• Microprocessor reset circuits in industrial control systems
• Power supply supervision in embedded computing devices
• System reset management in consumer electronics

Supervisors Procurement Notes

Verify the manufacturer designation matches Union Semiconductor International Limited. Confirm the suffix RP corresponds to the specific package and temperature grade required for your application. Request the official datasheet to validate pinout configuration and electrical characteristics against your design specifications before procurement.

Supervisors Selection Notes

Select this component when a dedicated 3-pin supervisor is required for microprocessor reset applications. Ensure the fixed threshold voltage aligns with the target system's operating range. Verify that the package type meets the PCB layout constraints and thermal requirements of the final assembly.

Supervisors Part Context

This part belongs to the UM803 series of 3-pin microprocessor reset circuits from Union Semiconductor. The series includes variants such as UM803JP, UM803JS, and UM803LP, which share similar functional descriptions but may differ in specific electrical parameters or packaging options defined by their respective suffixes.

Supervisors Replacement Considerations

Cross-reference with other UM803 variants like UM803JP or UM803LS if pin compatibility and threshold voltages match. Verify functional equivalence with generic 3-pin supervisors only after confirming specific electrical parameter alignment.
