R3111H431C-T1-FE

Supervisors Overview

The R3111H431C-T1-FE is a low voltage detector manufactured by Nisshinbo Micro Devices. It monitors a single input voltage with a threshold of 4.3V. The device features an open-drain output and provides a high-active reset signal. It operates within a temperature range of -40°C to 85°C and is housed in a SON1612-6 package.

Supervisors Feature Summary

• Monitors supply voltage against a fixed threshold
• Provides active-high reset signal via open-drain output
• Operates across extended industrial temperature ranges

Supervisors Applications

• Low voltage detection in portable electronic devices
• Power management monitoring in embedded systems
• Battery voltage supervision in consumer electronics

Supervisors Procurement Notes

Verify the specific suffix codes for packaging and tolerance requirements against official datasheets. Confirm the operating temperature range matches application needs. Ensure the SON1612-6 footprint aligns with PCB layout constraints. Cross-reference the manufacturer part number with authorized distributor listings to ensure authenticity and availability.

Supervisors Selection Notes

Select this component when a fixed 4.3V threshold is required for system supervision. Consider the open-drain output compatibility with downstream logic levels. Evaluate the SON1612-6 package size against available board space. Verify that the current consumption and reset delay characteristics meet the specific design timing requirements.

Supervisors Part Context

This part belongs to the R3111x series of voltage detectors from Nisshinbo Micro Devices. The series offers various threshold voltages and output configurations. The R3111H431C variant specifically targets applications requiring precise monitoring at the 4.3V level with standard reset timing characteristics.

Supervisors Replacement Considerations

Check for other R3111x variants with different thresholds or output types. Verify pinout compatibility before substituting with similar low voltage detectors from other manufacturers.
