BD49K25G-TL

Overview

The BD49K25G-TL is a standard voltage detector IC from ROHM Semiconductor, designed for monitoring supply voltages. It features a CMOS output type and operates within a reset active voltage range of 0.95V to 10V. The typical under-voltage detection voltage is 2.5V with a precision of ±1%. Circuit current consumption is specified at 0.60μA (VS=4.8V) in the ON state and 0.85μA in the OFF state. The device lacks manual reset, watchdog timer, and adjustable delay timer functions. It is housed in an SSOP-3 package and supports RoHS compliance.

Feature Summary

• CMOS output configuration for direct logic interface
• High detection accuracy with ±1% precision
• Ultra-low power consumption suitable for battery applications

Applications

• Processor supervisor circuits
• Battery voltage monitoring systems
• General purpose voltage supervision

Procurement Notes

Verify the specific ordering suffix TL against the required tape-and-reel quantity specifications. Confirm that the SSOP-3 package dimensions align with the target PCB footprint. Ensure the 2.5V threshold matches the system's critical voltage level requirements before finalizing the component selection.

Selection Notes

Select this component when a fixed 2.5V threshold is required without additional control features like manual reset or watchdog timers. The CMOS output is suitable for standard digital logic families. Consider the low current consumption for energy-sensitive designs where standby power is a constraint.
