BD46242G-TR

Overview

The BD46242G-TR is a voltage detector manufactured by ROHM Semiconductor, designed for monitoring single-channel supply voltages. It features a fixed threshold voltage of 2.4V with a precision of ±1%. The device provides a CMOS output type and supports manual reset functionality. Key electrical parameters include a maximum operating voltage of 10V, a reset delay time of 200ms, and a typical static current of 750nA. It operates within a temperature range of -40°C to +105°C and is housed in an SSOP-5 package.

Feature Summary

• Monitors a single input voltage channel with a fixed detection threshold.
• Provides a CMOS output signal for system reset control.
• Includes manual reset capability for controlled system recovery.

Applications

• Embedded systems requiring reliable power supply supervision
