BD49L52G-TL

Overview

The BD49L52G-TL is a CMOS voltage detector IC from the ROHM BD49 series, housed in an SSOP-3 package. It features a fixed detection threshold of 5.2V with ±1% accuracy and operates within a supply voltage range up to 10V. The device draws 900nA operating current and includes a 100us reset delay timer. It lacks manual reset, watchdog, or chip enable functions. Operating temperatures span -40°C to +105°C.

Feature Summary

• CMOS output interface for digital logic compatibility
• High precision voltage detection with 1% accuracy tolerance
• Ultra-low power consumption suitable for battery applications

Applications

• Processor supervisor circuits
• Battery backup switching systems
• Portable electronic device power management

Procurement Notes

Verify component authenticity through authorized channels as this part is marked as Last Time Buy. Confirm RoHS compliance status via official datasheets before integration. Check humidity sensitivity handling requirements during storage and assembly processes to ensure reliability.

Selection Notes

Select this component when a fixed 5.2V threshold is required without adjustable delay features. Consider the SSOP-3 footprint constraints and single-input monitoring capability. Evaluate if the absence of manual reset or watchdog functions aligns with system safety requirements.

Part Context

Part of the BD49xxx series of high-accuracy, low-current voltage detectors. This specific model provides a 5.2V detection point within the 2.3V to 6.0V available range increments. It serves as a specialized supervisory circuit for precise voltage monitoring in compact embedded designs.

Replacement Considerations

BD5250G-1TR is listed as a similar specification replacement, though it offers adjustable delay and different output characteristics.
