BD48L56G-TL

Overview

The BD48L56G-TL is a ROHM Semiconductor voltage detector IC in the BD48xxx series, designed for high-accuracy monitoring with low current consumption. It features an N-channel open-drain output and monitors a single input channel. The device triggers at a threshold voltage of 5.6 V with 1% accuracy and includes a reset delay time of 100 us. It operates within a supply voltage range up to 10 V and consumes only 900 nA of operating current. The component is housed in an SSOP-3 package and supports surface mount installation across a temperature range of -40 C to +105 C.

Feature Summary

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

Applications

• Portable electronic devices requiring efficient power management
• Battery-operated equipment needing voltage level supervision
• Embedded systems utilizing microcontrollers or memory circuits

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance details and moisture sensitivity handling requirements before procurement. Ensure replacement strategies are established as availability may be limited. Cross-reference datasheet specifications against design requirements to validate performance under operational conditions.

Selection Notes

Select this component when a fixed 5.6 V threshold is required for single-channel voltage monitoring. Consider the SSOP-3 package constraints for PCB layout and thermal dissipation. Evaluate the 100 us reset delay against system timing requirements. Compare against BD48LxxG-TL variants if different threshold voltages are needed while maintaining identical package and electrical characteristics.

Part Context

This part belongs to the BD48xxx series of highly accurate, low-current voltage detectors from ROHM Semiconductor. The series distinguishes itself by offering N-channel open-drain outputs in the BD48xxx line, contrasting with CMOS outputs in the BD49xxx line. These devices are engineered for supervisory roles in compact electronic designs where space and power efficiency are critical constraints.
