BU4216G-TR

Overview

The BU4216G-TR is a CMOS voltage detector with an adjustable reset delay time, designed for monitoring power supply voltages. It features a typical under-voltage detection threshold of 1.6V with ±1% precision and a hysteresis voltage of ±5mV. The device operates within a reset active voltage range of 0.7V to 7V and provides an open-drain output that activates at a low state. It consumes 0.40μA in the ON state and 0.55μA in the OFF state at Vdet=4.8V. Packaged in SSOP-5, it supports a minimum packing quantity of 3000 units.

Feature Summary

• Adjustable reset delay timer functionality
• Open-drain output type with low active state
• High precision voltage detection with hysteresis

Applications

• Power supply monitoring systems
• Microprocessor reset circuits
• Battery backup supervision

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging configuration. Confirm the component status as Not Recommended for New Designs (NRND) before finalizing procurement plans. Ensure compatibility with existing SSOP-5 footprints and validate the 1.6V threshold against system requirements.

Selection Notes

Select this component when an adjustable delay is required for reset sequencing. The low current consumption suits battery-operated applications. Verify the input voltage range covers the target supply rails. Consider the NRND status for long-term production viability.

Part Context

This part belongs to the BU42xxG series of voltage detectors from ROHM Semiconductor. It shares pinout and functional similarities with the BD5216G-1, which is recommended for new designs. The series focuses on low-power CMOS technology for efficient power management.

Replacement Considerations

The BD5216G-1 is listed as a similar level replacement with the same pinout and package. The BD5216G-1TR is the tape-and-reel variant of this substitute.
