BD48L32G-TL

Overview

The BD48L32G-TL is a voltage detector IC from ROHM Semiconductor, designed for monitoring single-input power supplies. It features an N-channel open-drain output and operates within a supply voltage range up to 10 V. The device detects voltages with a threshold of 3.2 V and maintains an accuracy of ±1%. It includes a reset delay time of 100 µs and consumes a typical operating current of 900 nA. The component is housed in a compact SSOP-3 package and supports an extended operating temperature range from -40°C to +105°C.

Feature Summary

• Provides precise voltage supervision with high detection accuracy
• Features low power consumption suitable for battery-operated systems
• Utilizes an open-drain output interface for flexible logic integration

Applications

• Processor supervisor circuits requiring stable voltage monitoring
• Battery-powered devices needing efficient power management
• Embedded systems utilizing CMOS logic interfaces

Procurement Notes

Verify the obsolete status and last-time-buy availability before design finalization. Confirm RoHS compliance and moisture sensitivity level requirements for your manufacturing process. Ensure the SSOP-3 footprint matches your PCB layout constraints. Check for any specific handling instructions related to the open-drain output configuration.

Selection Notes

Select this component when a fixed 3.2 V threshold is required for system supervision. Consider the 100 µs reset delay for timing-sensitive applications. Evaluate the 900 nA current draw against strict power budgets. Verify that the open-drain output suits the downstream logic levels without additional pull-up components.

Part Context

This part belongs to the BD48Lxx series of voltage detectors, characterized by high precision and low current consumption. The series offers various detection voltages in 0.1 V increments. The BD48L32G-TL specifically targets applications needing reliable reset signals for digital circuits within a wide temperature range.

Replacement Considerations

BD5232G-1TR is listed as a similar specification replacement. Note differences in package type (SSOP5 vs SSOP3) and reset delay characteristics. Verify pinout compatibility and electrical parameter alignment before substitution.
