BD5246G-2MTR

Overview

The BD5246G-2MTR is a voltage detector IC from Rohm Semiconductor, designed for monitoring supply voltages in electronic circuits. It features an adjustable delay timer and operates within a reset active voltage range of 0.8V to 6V. The typical under-voltage detection threshold is 4.6V with a precision of ±0.9%. It consumes ultra-low current, specified at 0.23µA when on and 0.27µA when off at Vdet=4.8V. The device provides an open-drain output with low-active reset state. It is housed in a compact SSOP5 package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Adjustable delay timer functionality without requiring external capacitors due to built-in counter timer circuitry.
• Ultra-low current consumption characteristics suitable for battery-powered or energy-efficient applications.
• High accuracy voltage detection with tight tolerance specifications for reliable system monitoring.

Applications

• Microcontroller reset circuits requiring precise voltage supervision.
• Logic circuit power management systems needing stable reset signals.
• Automotive electronic modules utilizing AEC-Q100 qualified components.

Procurement Notes

Verify the specific suffix '2MTR' against official Rohm documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for SSOP5 packages. Check for any recent lifecycle status updates such as last-time-buy notices or recommended replacements. Confirm RoHS compliance requirements match project standards. Validate that the adjustable delay feature meets timing constraints for the target application.

Selection Notes

Select this component when a fixed threshold voltage detector is insufficient and adjustable delay is required. Compare current consumption figures against other series members if power efficiency is critical. Consider the open-drain output capability for interfacing with various logic levels. Evaluate the operating temperature range against environmental conditions. Verify pinout compatibility with alternative parts like BD5246G-TR if supply chain flexibility is needed.

Part Context

This part belongs to the BD52xx series of voltage detectors from Rohm Semiconductor. It shares architectural similarities with other members like BD5246G-TR but differs in packaging and delay configuration options. The series is characterized by high accuracy and low power consumption. It serves as a specialized solution for power management in portable and automotive electronics where space and energy are constrained.

Replacement Considerations

BD5246G-TR is listed as a parameter equivalent substitute with the same pinout and package. BD48E46G-MTR is also identified as a parameter equivalent option within the manufacturer's lineup. Verify electrical parameters and package dimensions before substitution.
