BD46361G-TR

Overview

The BD46361G-TR is a voltage detector manufactured by ROHM Semiconductor, designed for monitoring power supply voltages. It features a fixed detection voltage of 3.6V with a precision of ±1%. The device operates within a reset active voltage range of 0.95V to 10V and utilizes a CMOS output type. It includes a manual reset function and a fixed delay timer of 100msec. The circuit current is 0.80μA when on (at Vdet=4.8V) and 0.85μA when off. It supports an hysteresis voltage feature and functions in temperatures from -40°C to +105°C. The component is housed in an SSOP-5 package.

Feature Summary

• Integrates a fixed delay timer for stable reset signal generation
• Supports manual reset functionality for system control
• Provides CMOS output compatible with digital logic interfaces

Applications

• Microprocessor reset circuits
• Battery-powered device supervision
• Portable equipment power management

Procurement Notes

Verify the specific suffix G-TR against official ROHM documentation to confirm package and tape-and-reel specifications. Confirm end-of-life status as the base model BD46361G is listed as NRND. Ensure compatibility with existing board layouts using the SSOP-5 footprint. Cross-reference electrical parameters with the latest datasheet before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 3.6V threshold with a 100msec delay is required. The CMOS output and manual reset capability distinguish it from open-drain or adjustable-delay alternatives. Consider the operating temperature range and low standby current for battery-sensitive applications. Verify that the SSOP-5 package fits the mechanical constraints of the target design.

Part Context

The BD46361G belongs to the BD46 series of voltage detectors from ROHM. This series focuses on providing reliable supervision for embedded systems with minimal power consumption. The part is often compared to similar models like the BD5236G-1, which offers adjustable delay times instead of fixed delays.

Replacement Considerations

The BD5236G-1 is a confirmed substitute with the same package but different delay characteristics.
