BD49K24G-TL

Overview

The BD49K24G-TL is a CMOS output voltage detector IC from the ROHM BD49 series, designed for processor supervision. It features a fixed detection threshold of 2.4V with ±1% accuracy and operates within a supply voltage range of 0.95V to 10V. The device provides a low-active reset signal with a 100µs delay timer and includes hysteresis functionality. Packaged in an SSOP-3 format, it supports surface-mount installation and functions across a temperature range of -40°C to +105°C.

Feature Summary

• CMOS output architecture providing low power consumption
• High precision voltage detection with fixed threshold options
• Integrated reset delay timer for stable system initialization

Applications

• Processor supervisor circuits
• Battery voltage monitoring systems
• Portable electronic devices requiring low current operation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific moisture sensitivity level requirements during storage and handling. Ensure the ordering suffix matches the required package configuration before finalizing procurement orders.

Selection Notes

Select this component when a fixed 2.4V threshold is required for single-input voltage monitoring. Consider the SSOP-3 package constraints and CMOS output drive capabilities against system interface requirements. Evaluate the 100µs reset delay against target microcontroller startup times.

Part Context

This part belongs to the BD49 series of high-accuracy, low-current voltage detectors. The series offers various fixed detection voltages ranging from 2.3V to 6.0V in 0.1V increments. All family members share similar operational characteristics including CMOS outputs and compact packaging solutions.

Replacement Considerations

BD5224G-1TR is listed as a recommended replacement with similar specifications, though it utilizes an SSOP-5 package instead of SSOP-3.
