BD49K30G-TL

Overview

The BD49K30G-TL is a CMOS voltage detector IC from the BD49 series, designed for monitoring supply voltages in the range of 2.3V to 6.0V with 0.1V increments. It features a fixed detection threshold of 3.0V and provides an active-low reset output. The device operates within a power supply range up to 10V, consumes low current (typically 900nA), and offers high accuracy of ±1%. It includes a 100µs reset delay timer and functions across an extended temperature range of -40°C to +105°C.

Feature Summary

• CMOS output structure for low power consumption
• High precision voltage detection with ±1% accuracy
