BD49E34G-TR

Overview

The BD49E34G-TR is a CMOS output voltage detector from ROHM Semiconductor, featuring a fixed threshold of 3.4V and ±1% accuracy. It operates within a supply voltage range of -0.3V to 10V with a reset delay of 100µs. The device consumes 900nA current and functions between -40°C and +105°C in an SSOP-5 package.

Feature Summary

• CMOS output type for digital interface compatibility
• High detection accuracy of ±1%
• Low power consumption suitable for battery applications

Applications

• Processor supervisor circuits
• Battery backup switching systems
• Portable electronic devices requiring low quiescent current

Procurement Notes

Verify the NRND status before procurement as this component is not recommended for new designs. Confirm the SSOP-5 package availability and ensure the 3.4V threshold aligns with system requirements. Check RoHS compliance documentation for regulatory adherence.

Selection Notes

Select this part for single-input monitoring where precise 3.4V detection is critical. The CMOS output simplifies logic interfacing compared to open-drain alternatives. Ensure the operating temperature range meets environmental constraints.

Part Context
