BD5240G-TR

Overview

The BD5240G-TR is a voltage detector manufactured by ROHM Semiconductor, designed for power management applications. It features an open-drain output and operates within a supply voltage range up to 7 V. The device monitors a single input with a threshold voltage of 4.0 V and includes an adjustable delay timer function. It is housed in a compact SSOP-5 package and supports surface mount installation. The component functions as a supervisory circuit without manual reset or watchdog capabilities.

Feature Summary

• Adjustable delay timer functionality for customized reset timing
• Open-drain output configuration for flexible interfacing
• Compact SSOP-5 surface-mount package design

Applications

• Processor supervisor circuits
• Power supply monitoring systems
• Voltage detection in electronic devices

Procurement Notes

Verify the specific ordering suffix and package type when sourcing. Confirm RoHS compliance status and check current supply availability as this part may be subject to production lifecycle changes. Ensure the selected variant matches the required electrical specifications for your design.

Selection Notes

Select this component for applications requiring a 4.0 V detection threshold with adjustable reset delays. Consider the open-drain output and SSOP-5 package constraints. Evaluate compatibility with system voltage ranges and temperature requirements before integration into the final product design.

Part Context

This voltage detector belongs to ROHM's standard voltage detector series. It serves as a replacement for older models like the BD4840G, offering similar pinouts but with enhanced features such as adjustable delay timers. The BD5240G-1TR is a recommended alternative for new designs within the same family.

Replacement Considerations

The BD5240G-1TR is a recommended replacement with the same package and similar specifications. The BD4840G is listed as not recommended for new designs but shares the same package.
