BD48L52G-TL

Overview

The BD48L52G-TL is a voltage detector IC from the ROHM BD48 series, designed for monitoring single power supply lines. It features an N-channel open-drain output and operates within a maximum supply voltage of 10 V. The device detects voltages with high accuracy, specified at 1%, and includes a reset delay time of 100 us. It functions in a temperature range from -40 C to +105 C while consuming only 900 nA of operating current. The component is housed in a compact SSOP-3 package suitable for surface mount applications.

Feature Summary

• Provides precise voltage supervision with 1% detection accuracy
• Utilizes low-power architecture with 900 nA operating current consumption
• Features N-channel open-drain output for flexible logic interfacing
• Operates reliably across extended industrial temperature ranges

Applications

• Processor supervisor circuits requiring stable voltage monitoring
• Battery-powered systems needing ultra-low quiescent current
• Industrial control units operating in wide temperature environments
• Portable electronic devices with limited power budgets

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolete status. Confirm RoHS compliance documentation matches specific batch requirements. Check datasheet revisions for any parameter updates prior to integration. Ensure storage conditions account for humidity sensitivity classification. Validate pinout compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component when fixed threshold detection near 5.2 V is required without manual reset functionality. Consider the open-drain output capability for level shifting needs. Evaluate the 100 us reset delay against system startup timing constraints. Compare power consumption benefits against alternative supervisors in similar packages. Assess thermal performance within the specified -40 C to +105 C operational window.

Part Context

This part belongs to the BD48xxx series of highly accurate, low-current voltage detectors. The series offers various detection voltages from 2.3 V to 6.0 V in 0.1 V increments. Devices in this family share common characteristics such as open-drain outputs and minimal standby current. The BD48L52G-TL specifically targets applications requiring precise monitoring around the 5.2 V threshold.
