BU4316G-TR

Overview

The BU4316G-TR is a CMOS voltage detector from ROHM Semiconductor, designed for monitoring single-channel input voltages. It features an adjustable reset delay timer and operates within a supply voltage range of 0.7 V to 7 V. The device provides a typical under-voltage detection threshold of 1.6 V with ±1% precision. Key electrical characteristics include a maximum operating current of 550 nA and a static current of 350 nA. It utilizes an SSOP-5 surface-mount package and supports an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• CMOS output structure for low power consumption
• Adjustable reset delay timer functionality
• High accuracy voltage detection with hysteresis

Applications

• Portable equipment battery monitoring
• Microprocessor system reset circuits
• Low voltage detection in consumer electronics

Procurement Notes

Verify the obsolete status before procurement as this component is not recommended for new designs. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing PCB footprints if replacing older inventory. Check RoHS compliance documentation for specific manufacturing batches. Validate lead times carefully due to potential discontinuation risks.

Selection Notes

Select this component when a fixed 1.6 V threshold with high precision is required. The adjustable delay feature allows customization for specific system startup requirements. Consider the low standby current for battery-operated applications. Verify that the SSOP-5 package fits the design constraints. Evaluate the BD5216G-1 as a potential replacement if new design support is necessary.

Part Context

This part belongs to the BU42(43)xxG series of supervisory circuits. It is manufactured by ROHM Semiconductor and is classified as a voltage detector. The device is intended for general-purpose power management applications requiring reliable voltage supervision.

Replacement Considerations

The BD5216G-1 is listed as a similar level replacement with the same pinout. Note that the replacement uses an SSOP-5 package while the original may vary. Verify supply status and datasheet updates for the substitute part.
