BD46E241G-MTR

Overview

The BD46E241G-MTR is a CMOS output voltage detector IC designed for automotive applications, featuring a fixed delay timer. It operates within a supply voltage range of 0.95V to 10V with a typical threshold voltage of 2.4V and ±1% precision. The device includes a manual reset function and delivers a low-active reset signal after a fixed 100ms delay. It consumes 0.80µA in the active state and 0.85µA in the standby state at Vdet=4.8V. Packaged in an SSOP-5 form factor, it supports functional safety analysis.

Feature Summary

• Built-in counter timer delay circuit eliminates the need for external capacitors
• High accuracy voltage detection with ±1% precision
• Low current consumption suitable for battery-backed systems
• Manual reset capability for system control

Applications

• Automotive electronic control units (ECUs)
• Battery backup power monitoring
• Microprocessor reset circuits
• Power management supervisory systems

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notifications as this series may be subject to discontinuation. Ensure packaging matches reel specifications for surface mount assembly processes.

Selection Notes

Select this component when a fixed 100ms delay is required without external timing components. Choose based on the 2.4V threshold requirement and CMOS output drive capability. Consider the SSOP-5 package constraints and operating temperature range of -40°C to +105°C for automotive environments.

Part Context
