BD48L25G-TL

Overview

The BD48L25G-TL is a standard voltage detector IC from ROHM Semiconductor, designed for precise power supply monitoring. It features an N-channel open-drain output and operates within a supply voltage range of 0.95V to 10V. The device provides a typical under-voltage detection threshold of 2.5V with a high precision of ±1%. It consumes low circuit current, specified as 0.60μA in the ON state and 0.85μA in the OFF state at Vs=4.8V. The component supports a reset active voltage range of 0.95V to 10V and includes hysteresis defined as Vs x 0.05. It is housed in a compact SSOP3 package measuring 2.9x2.8mm with a thickness of 1.25mm, suitable for surface mount applications across a temperature range of -40°C to 105°C.

Procurement Notes

Verify the specific ordering part number BD48L25G-TL against official ROHM documentation to confirm availability status. Check for any last-time-buy notices or end-of-life declarations prior to procurement. Ensure compatibility with the required SSOP3 package dimensions and thermal specifications. Confirm RoHS compliance requirements match project standards. Validate that the 2.5V detection threshold aligns precisely with system design needs.

Selection Notes

Select this component when a fixed 2.5V detection threshold is required with high accuracy. Consider the SSOP3 package size constraints and pin rotation characteristics. Evaluate the open-drain output capability against pull-up resistor requirements in the target circuit. Assess the operating temperature range suitability for the intended environmental conditions. Compare the low current consumption benefits against other supervisory options.
