R3117N263A-TR-YE

Supervisors Overview

The R3117N263A-TR-YE is a low voltage detector manufactured by Nisshinbo Micro Devices, designed for industrial applications. It features a SOT-23-5 surface-mount package and operates within a supply voltage range of 1 V to 6 V. The device monitors a single input with a threshold voltage of 2.6 V. It utilizes an open-drain output type and includes a backup battery switch function. Key electrical parameters include a reset delay time of 40 µs and a maximum power dissipation of 420 mW. The component functions without manual reset or watchdog timer capabilities.

Supervisors Feature Summary

• Integrates a dedicated sense pin for precise voltage monitoring in industrial environments
• Supports backup battery switching functionality for continuous operation during power transitions
• Delivers high accuracy in voltage supervision with a compact SMD/SMT footprint

Supervisors Applications

• Industrial system voltage supervision
• Backup battery management circuits
• Low voltage detection for microprocessor resets

Supervisors Procurement Notes

Verify the specific suffix 'YE' against official Nisshinbo documentation to confirm packaging and tape-and-reel specifications. Ensure the operating temperature range of -40°C to +105°C aligns with your environmental requirements. Confirm that the open-drain output configuration matches your downstream logic interface needs before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a 2.6 V threshold is required for systems operating between 1 V and 6 V. The SOT-23-5 package suits space-constrained designs. Consider the 40 µs reset delay for timing-sensitive applications. Verify compatibility with open-drain outputs if interfacing with CMOS logic levels directly.

Supervisors Part Context

This part belongs to the R3117N series of voltage detectors from Nisshinbo Micro Devices. The series is characterized by low current consumption and high accuracy. The R3117N263A variant specifically targets applications requiring a 2.6 V detection level. It is distinct from automotive-specific variants like the NV3600 series which feature higher voltage ratings.

Supervisors Replacement Considerations

Cross-reference with other R3117N series parts for different thresholds. Verify package compatibility with SOT-23-5 alternatives. Check datasheets for identical reset delay and output type specifications to ensure functional equivalence.
