BD5325G-TR

Overview

The BD5325G-TR is a voltage detector IC from the BD53xx series manufactured by ROHM Semiconductor. It features a detection threshold of 2.5V with an accuracy of ±1%. The device operates within a supply voltage range of 0.95V to 10V and supports an adjustable delay timer for reset timing control. It utilizes a CMOS output type with low active state and lacks manual reset or watchdog functions. The component is housed in a 5-SSOP package, suitable for surface mount installation, and functions across a temperature range of -40°C to +105°C.

Feature Summary

• Provides precise voltage monitoring with a fixed 2.5V detection threshold and high accuracy.
• Includes an adjustable delay timer circuit allowing customizable reset timing intervals.
• Features a compact SSOP-5 package design optimized for space-constrained surface mount applications.

Applications

• Microprocessor system power supply supervision
• Battery-operated equipment voltage monitoring
• Portable electronic device power management

Procurement Notes

Verify current availability status as the component may be discontinued or not recommended for new designs. Confirm package integrity and RoHS compliance upon receipt. Cross-reference ordering numbers carefully to ensure correct variant selection. Check for alternative recommended parts if this specific model is no longer supported by the manufacturer.

Selection Notes

Select this component when a fixed 2.5V threshold with adjustable delay is required. Ensure the application voltage stays within the 0.95V to 10V operating range. Consider the CMOS output drive capability and temperature specifications against system requirements. Verify that the lack of manual reset functionality aligns with the system design needs.

Part Context

This part belongs to the BD53xx series of simple reset/voltage detectors. It shares the SSOP-5 package form factor with other variants in the family but differs in threshold voltage and output characteristics. It serves as a supervisory circuit for ensuring stable operation of digital logic systems under varying power conditions.

Replacement Considerations

BD5225G-1TR is listed as a replacement with the same pinout and package. Note differences in output type (open drain vs CMOS) and operating voltage range before substitution.
