R3111D361A-TR-FE

Supervisors Overview

The R3111D361A-TR-FE is a single-channel voltage detector manufactured by Nisshinbo Micro Devices Inc. It operates within a supply voltage range of 0.7 V to 10 V and features a fixed detection threshold of 3.6 V. The device provides an open-drain output with active-low reset signaling and includes a maximum reset timeout of 100 µs. Packaged in a compact SOT-23-5 surface-mount case, it supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides low-voltage monitoring with an open-drain output interface for system supervision
• Features a fixed detection threshold for precise voltage level tracking without external components
• Includes a built-in reset timeout circuit to ensure stable power-up sequences

Supervisors Applications

• Portable electronic devices requiring battery voltage monitoring
• Embedded systems needing reliable power-on reset generation
• Industrial control units operating under variable supply conditions

Supervisors Procurement Notes

Verify the specific suffix codes against official datasheets to confirm package type and thermal characteristics. Ensure compatibility with existing PCB footprints, particularly for the SOT-23-5 variant. Cross-reference RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 3.6 V threshold is required for single-supervision applications. Consider the low quiescent current and small footprint for space-constrained designs. Verify that the open-drain output configuration aligns with the pull-up resistor requirements of the connected microcontroller or logic circuitry.

Supervisors Part Context

This part belongs to the R3111x series of supervisory circuits designed for efficient power management. The series offers various threshold options packaged in small form factors like SOT-23-5 and SON1612-6. These devices are engineered for low-power consumption and high accuracy in portable and industrial electronics.

Supervisors Replacement Considerations

Check for other R3111x variants with different threshold voltages if system requirements change. Verify pinout compatibility with alternative manufacturers' voltage detectors offering similar open-drain outputs and reset timing characteristics.
