BD5210G-1TR

Overview

The BD5210G-1TR is a voltage detector IC from ROHM Semiconductor designed for monitoring power supply voltages. It features an adjustable reset delay timer and operates within a detection voltage range of 0.8 V to 6 V with a typical threshold of 1.0 V. The device provides an open-drain output and consumes ultra-low current, specified at 0.23 μA in the ON state and 0.27 μA in the OFF state at VDET=4.8 V. It supports a supply voltage up to 7 V and functions across a temperature range of -40°C to +105°C.

Feature Summary

• Ultra-low current consumption for extended battery life
• Adjustable reset delay timer functionality
• Open-drain output configuration
• Wide operating voltage range support

Applications

• Portable electronic devices requiring low power monitoring
• Battery-powered systems with voltage supervision needs
• General purpose voltage detection in embedded circuits

Procurement Notes

Verify the specific suffix '1TR' corresponds to the 1.0V threshold variant and SSOP-5 package when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure design-in compatibility with the required reset delay timing characteristics.

Selection Notes

Select this component when a fixed 1.0V threshold with adjustable delay is required. Compare against BU4310G for similar performance but note the BD5210G-1TR is recommended for new designs while the BU4310G is not. Consider the open-drain output requirement for interface compatibility with the host system logic levels.

Part Context

This part belongs to the BD52xxG series of nano-energy voltage detectors. It serves as a modern replacement for older ROHM models like the BU4310G and BU4910G, which are marked as not recommended for new designs. The series emphasizes low power consumption and compact packaging for portable applications.

Replacement Considerations

The BU4310G is listed as a similar level part with the same pinout and package but is not recommended for new designs. The BU4910G shares the same package but lacks the adjustable delay feature.
