BD49L48G-TL

Overview

The BD49L48G-TL is a CMOS voltage detector IC from ROHM Semiconductor, featuring a fixed detection threshold of 4.8V and a CMOS output type. It operates within a supply voltage range up to 10V with a reset delay time of 100µs. The device offers high accuracy of ±1% and consumes only 900nA of operating current. It is housed in an SSOP-3 package and functions across a temperature range of -40°C to +105°C.

Feature Summary

• CMOS output configuration for direct logic interface compatibility
• High precision voltage detection with ±1% accuracy tolerance
• Ultra-low power consumption suitable for battery-operated systems

Applications

• Portable electronic devices requiring low standby current
• Battery-powered equipment needing reliable under-voltage monitoring
• Embedded systems utilizing standard CMOS logic families

Procurement Notes

Verify component authenticity through authorized channels as the part is marked obsolete. Confirm package integrity and pin alignment against original specifications before integration. Ensure storage conditions meet humidity sensitivity requirements to prevent degradation prior to assembly.

Selection Notes

Select this component when a fixed 4.8V threshold with CMOS output is required. Consider the SSOP-3 footprint constraints and thermal performance limits. Evaluate if the 100µs reset delay meets system timing requirements compared to adjustable alternatives.

Part Context

This model belongs to the BD49xxx series of highly accurate, low-current voltage detectors. It complements the BD48xxx series which features N-channel open-drain outputs. Both series share similar accuracy and power characteristics but differ in output stage design for specific logic interfacing needs.

Replacement Considerations

BD49K48G-TL serves as a verified substitute within the same series offering identical electrical parameters and package dimensions.
