BD48K56G-TL

Overview

The BD48K56G-TL is a standard CMOS voltage detector IC manufactured by ROHM Semiconductor. It features an N-channel open-drain output and provides a typical under-voltage detection threshold of 5.6V with ±1% precision. The device operates within a reset active voltage range of 0.95V to 10V. It consumes 0.60μA in the ON state and 0.85μA in the OFF state at Vs=4.8V. The component is housed in an SSOP3 package, supports a supply voltage up to 10V, and functions across a temperature range of -40°C to +105°C.

Feature Summary

• Standard CMOS voltage detection architecture with high accuracy
• N-channel open-drain output configuration for flexible interfacing
• Ultra-low power consumption suitable for battery-operated systems
• Compact SSOP3 package design with single ground pin rotation

Applications

• Processor supervisor circuits requiring precise voltage monitoring
• Battery-powered electronic devices needing low standby current
• General-purpose voltage supervision in industrial control systems

Procurement Notes

Verify the specific ordering suffix TL against the required tape-and-reel quantity specifications. Confirm that the SSOP3 package dimensions align with the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the RoHS compliance status with current regulatory standards before procurement.

Selection Notes

Select this component when a fixed 5.6V detection threshold is required with minimal quiescent current. The open-drain output allows for easy level shifting or wired-OR connections. Consider the ±1% precision tolerance for applications demanding strict voltage limits. Evaluate the 100us reset delay timer absence if immediate response is critical.

Part Context

This part belongs to the BD48 series of highly accurate, low-current voltage detectors from ROHM. The series offers various detection voltages in 0.1V increments. The BD48K56G-TL specifically targets applications needing reliable supervision around the 5.6V mark. It complements other parts like the BD48K48G-TL and BD48K53G-TL within the same family.

Replacement Considerations

The BD5250G-1TR is listed as a similar specification replacement. Note that the substitute uses an SSOP5 package instead of SSOP3, requiring layout adjustments. Verify compatibility regarding the slightly different detection voltage (5.0V vs 5.6V) and precision specifications.
