Overview
The BD4849G-TR is a standard voltage detector IC from the BD48 series by Rohm Semiconductor. It features an N-channel open-drain output and monitors a single input voltage with a typical threshold of 4.9V. The device operates within a supply voltage range up to 10V and provides a reset signal that is active low. It is designed for surface-mount installation in SSOP-5 packages, supporting automated tape-and-reel handling.
Feature Summary
- Provides precise under-voltage detection with high accuracy
- Features an N-channel open-drain output for flexible interfacing
- Delivers a low-active reset signal upon voltage fault detection
Applications
- Processor supervisor circuits requiring stable power monitoring
- Embedded systems needing reliable voltage threshold detection
- Industrial control units utilizing single-channel supervision
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and lead times prior to order placement. Ensure compatibility with existing design specifications regarding voltage thresholds and output configurations before finalizing procurement decisions.
Selection Notes
Select this component when a fixed 4.9V detection threshold is required for system supervision. Consider the open-drain output capability for level shifting or wired-OR connections. Evaluate the SSOP-5 footprint constraints against available PCB real estate during the initial design phase.
Part Context
This part belongs to the BD48xxx series of highly accurate, low-current voltage detectors. The series offers various detection voltages ranging from 2.3V to 6.0V in 0.1V increments. These devices are designed for applications requiring precise monitoring with minimal power consumption.
Replacement Considerations
The BD5249G-1 is listed as a similar level replacement with the same package type. Verify electrical parameter alignment and supply status changes before substituting, as the original part may be not recommended for new designs.
