BD48L34G-TL

Overview

The BD48L34G-TL is a voltage detector IC from the ROHM BD48xxx series, designed for monitoring single-input supply voltages. It features an N-channel open-drain output and operates within a maximum supply voltage of 10 V. The device detects under-voltage conditions with a typical threshold of 3.4 V and maintains an accuracy of ±1%. It includes a fixed reset delay time of 100 µs and consumes a typical operating current of 900 nA. The component supports a wide operating temperature range from -40°C to +105°C and is housed in an SSOP-3 package.

Feature Summary

• Provides high-accuracy voltage monitoring with ±1% detection precision for reliable system supervision.
• Features low-current consumption suitable for battery-powered or energy-efficient applications.
• Utilizes an N-channel open-drain output interface for flexible logic level compatibility.

Applications

• Monitoring power supply rails in portable electronic devices
• Supervising voltage levels in embedded control systems
• Providing reset signals for microcontrollers during brown-out events

Procurement Notes

Verify availability status as this component may be obsolete or subject to last-time-buy restrictions. Confirm RoHS compliance details through official documentation before integration. Ensure design-in compatibility with existing SSOP-3 footprints and validate thermal performance within the specified operating temperature range.

Selection Notes

Select this part when a single-channel voltage monitor with open-drain output is required. Compare against BD48K34G-TL if different packaging or specific hysteresis characteristics are needed. Consider BD5234G-1 as a recommended replacement if similar specifications are acceptable but newer inventory is preferred.

Part Context

This device belongs to the BD48xxx series of highly accurate, low-current voltage detectors. The family distinguishes between BD48xxx devices with N-channel open-drain outputs and BD49xxx devices with CMOS outputs. The BD48L34G-TL specifically targets applications requiring precise under-voltage detection with minimal power consumption.

Replacement Considerations

BD5234G-1TR is listed as a recommended replacement with similar specifications. Note that the replacement uses an SSOP-5 package instead of SSOP-3, requiring footprint adaptation.
