R3112N141C-TR-FE

Supervisors Overview

The R3112N141C-TR-FE is a supervisory circuit from the Nisshinbo R3112N series, functioning as a low voltage detector with an output delay. It operates within a supply voltage range up to 6 V and features a threshold voltage of 1.4 V. The device provides a reset delay time of 100 ms and maintains accuracy within 2%. It consumes a working power supply current of 700 nA and supports a maximum power dissipation of 420 mW. Designed for surface mount installation, it is housed in an SOT-23-5 package and operates reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a fixed threshold voltage detection mechanism with a dedicated output capacitor type delay function to prevent false resets during transient power fluctuations.
• Provides a CMOS output interface that ensures compatibility with standard digital logic circuits while maintaining low quiescent current consumption.
• Supports backup battery switching applications through its specific low-voltage detection capabilities without requiring manual reset or watchdog timer functions.

Supervisors Applications

• Monitoring battery voltage levels in portable electronic devices to trigger low-battery warnings.
• Providing power-fail detection signals for microcontroller systems to initiate safe shutdown procedures.
• Acting as a supervisor for embedded systems requiring stable power sequencing during startup and operation.

Supervisors Procurement Notes

Verify the exact suffix codes against official Nisshinbo Micro Devices documentation to ensure correct threshold voltage and package configuration. Confirm RoHS compliance status and manufacturing origin details prior to ordering. Cross-reference the part number with authorized distributor catalogs to validate availability and lead times. Ensure storage conditions meet moisture sensitivity level requirements for surface-mount components.

Supervisors Selection Notes

Select this component when a precise 1.4 V detection threshold is required for low-voltage monitoring applications. Consider the 100 ms output delay feature if system stability against short-duration voltage dips is critical. Evaluate the 700 nA current consumption against total system power budgets for battery-operated designs. Verify that the SOT-23-5 package dimensions fit within the available PCB real estate constraints.
