R3132Q45EA-TR-FE

Supervisors Overview

The R3132Q45EA-TR-FE is a low voltage detector manufactured by Nisshinbo Micro Devices. It operates within a supply voltage range up to 6 V and functions reliably between -40°C and +85°C. The device features a fixed threshold voltage of 4.5 V with a reset delay time of 240 ms. It utilizes an SC-82AB-4 package and provides a CMOS open drain output. The component supports manual reset functionality and includes a battery backup switch, making it suitable for precise power monitoring applications.

Supervisors Feature Summary

• Integrates a built-in delay circuit to ensure stable reset signal generation during power transitions.
• Supports manual reset operations for enhanced system control and functional safety requirements.
• Includes a dedicated battery backup switch to maintain critical state retention during power interruptions.

Supervisors Applications

• Low voltage detection in portable electronic devices
• Power monitoring for microcontroller systems requiring manual reset
• Battery-powered equipment with backup switching needs

Supervisors Procurement Notes

Verify the exact threshold voltage and package type against the official datasheet before procurement. Confirm that the specific suffix matches the required electrical characteristics and packaging format. Ensure compatibility with the target operating temperature range and supply voltage limits. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Supervisors Selection Notes

Select this component when a fixed 4.5 V threshold is required for power supervision. Consider the SC-82AB-4 package size for space-constrained designs. Evaluate the need for manual reset and battery backup features against alternative variants without these functions. Ensure the 240 ms delay aligns with system startup timing requirements.

Supervisors Part Context

This part belongs to the R3132Q series of low voltage detectors from Nisshinbo Micro Devices. The series offers various threshold voltages and package options to suit different application needs. The Q-series typically features specific output types and additional functions like backup switches, distinguishing it from other series variants.

Supervisors Replacement Considerations

Check for parts with identical 4.5 V thresholds and compatible packages. Verify that substitute components support manual reset and battery backup if these features are critical. Ensure the replacement maintains the same operating temperature range and supply voltage specifications.
