BD48L57G-TL

Overview

The BD48L57G-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 typical threshold of 5.7 V and maintains an accuracy of 1%. It consumes only 900 nA of operating current and includes a reset delay time of 100 us. The component functions reliably across a temperature range of -40 C to +105 C and is housed in an SSOP-3 package.

Feature Summary

• Provides high-accuracy voltage detection with 1% precision for reliable system supervision.
• Features ultra-low current consumption of 900 nA to extend battery life in portable applications.
• Utilizes an N-channel open-drain output interface for flexible logic compatibility.

Applications

• Portable electronic devices requiring low-power voltage supervision
• Battery-operated systems needing efficient power management
• General-purpose circuit monitoring where minimal quiescent current is critical

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance details via official datasheets. Check humidity sensitivity handling requirements during storage and assembly. Ensure replacement strategies are evaluated as the part is no longer actively manufactured by ROHM Semiconductor.

Selection Notes

Select this component when low standby current and precise voltage monitoring are required. The SSOP-3 package suits space-constrained designs. Consider the fixed 5.7 V threshold and lack of manual reset or watchdog features during design integration. Verify that the open-drain output meets the downstream logic level requirements.

Part Context

This part belongs to the BD48xxx series of highly accurate, low-current voltage detectors. The series distinguishes itself with N-channel open-drain outputs, contrasting with the BD49xxx series which offers CMOS outputs. These devices are engineered for efficiency and precision in supervisory roles.

Replacement Considerations

BD48L56G-TL: Similar threshold (5.6 V), same package, open-drain output. BD48L54G-TL: Similar threshold (5.4 V), same package, open-drain output. BD48L49G-TL: Lower threshold (4.9 V), same package, open-drain output. All listed alternatives share the SSOP-3 package and open-drain configuration but differ in detection voltage thresholds.
