BD48L23G-TL

Overview

The BD48L23G-TL is a highly accurate, low-current voltage detector IC from the ROHM BD48xxx series. It features an N-channel open-drain output and monitors a single input channel with a detection threshold of 2.3V. The device operates within a supply voltage range up to 10V and offers 1% accuracy. It includes a fixed reset delay time of 100µs and consumes only 900nA of operating current. The component is housed in a compact SSOP-3 package and functions reliably across a temperature range of -40°C to +105°C.

Feature Summary

• Provides precise voltage monitoring with high accuracy for system supervision
• Features ultra-low power consumption suitable for battery-operated applications
• Utilizes an N-channel open-drain output for flexible interface compatibility

Applications

• Processor supervisor circuits requiring stable voltage monitoring
• Battery-powered devices needing extended operational life through low current draw
• Portable electronic equipment utilizing compact surface-mount packaging

Procurement Notes

Verify the specific suffix TL indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation. Check current lifecycle status as some listings indicate end-of-life or last-time-buy conditions. Ensure the SSOP-3 package variant matches your PCB footprint requirements before procurement.

Selection Notes

Select this component when a fixed 2.3V detection threshold is required for system supervision. Consider the 100µs reset delay for timing-sensitive applications. Evaluate the 900nA quiescent current against total system power budgets. Verify that the N-channel open-drain output aligns with the pull-up requirements of the connected logic circuitry.

Part Context

This part belongs to the BD48xxx series of voltage detectors characterized by high precision and minimal current consumption. The series offers various detection voltages from 2.3V to 6.0V in 0.1V increments. All devices in this family share similar electrical characteristics and package options, differing primarily in their specific detection thresholds.

Replacement Considerations

BD48K23G-TL: Similar specification with identical detection voltage but different ordering suffix.
