BD46462G-TR

Overview

The BD46462G-TR is a voltage detector with a fixed delay time manufactured by ROHM Semiconductor. It features an under-voltage detection threshold of 4.6V with ±1% precision. The reset active voltage range spans from 0.95V to 10V, utilizing a CMOS output type. A fixed delay timer of 200msec is integrated for reset timing. The device supports manual reset functionality and operates within a temperature range of -40°C to 105°C. Current consumption is 0.80μA in the ON state and 0.85μA in the OFF state at VDET=4.8V. Hysteresis is set at VDET x 0.05. Output currents are 1.2mA (Low) and 5mA (High).

Feature Summary

• Integrates a fixed 200msec delay timer for controlled reset timing.
• Supports manual reset functionality for system control.
• Provides CMOS output with defined low and high current capabilities.

Applications

• General purpose voltage monitoring in electronic circuits.
• System reset generation with fixed timing requirements.
• Power supply supervision in industrial or consumer electronics.

Procurement Notes

Verify the specific ordering suffix TR for tape-and-reel packaging configuration. Confirm that the component status is Last Time Buy, indicating limited future availability. Ensure compatibility with the SSOP5 package dimensions and thermal characteristics required by the target design. Cross-reference the exact threshold voltage tolerance against system requirements.

Selection Notes

Select this component when a fixed 200msec reset delay is mandatory rather than adjustable. The CMOS output interface suits logic-level interfacing needs. Consider the 10V maximum operating voltage for higher voltage applications compared to lower-rated alternatives. Verify the manual reset pin requirement aligns with the system architecture.

Part Context

This part belongs to the BD46 series of supervisory circuits from ROHM Semiconductor. It is designed for single-channel voltage monitoring applications. The device serves as a replacement or alternative in designs requiring precise voltage detection with deterministic reset delays. It complements other ROHM voltage detectors offering different delay or output configurations.

Replacement Considerations

BD5246G-1 is listed as a recommended replacement with the same package and similar specifications, though it features an adjustable delay and open-drain output instead of fixed delay and CMOS.
