BD46342G-TR

Overview

The BD46342G-TR is a voltage detector from the BD46xxx series manufactured by ROHM Semiconductor. It features a fixed delay time of 200ms and supports manual reset functionality. The device operates within a supply voltage range of 0.95V to 10V with a typical under-voltage detection threshold of 3.4V. It utilizes an SSOP5 package and maintains low power consumption, drawing 0.80μA in the ON state and 0.85μA in the OFF state at VDET=4.8V.

Feature Summary

• Provides a fixed 200ms reset delay timer for stable power-up sequencing.
• Includes manual reset capability for system control flexibility.
• Offers high precision voltage detection with ±1% accuracy.
• Supports operation across a wide temperature range from -40°C to 105°C.

Applications

• Processor supervisor circuits requiring precise voltage monitoring
• Portable equipment power management systems
• Battery-operated devices needing low standby current

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notices, as this part may be subject to discontinuation. Ensure packaging specifications match design requirements before finalizing procurement orders.

Selection Notes

Select this component when a fixed delay timer and manual reset are required alongside high detection accuracy. Compare against the BD5234G-1 if adjustable delay times are needed instead of fixed timing. Consider the operating voltage range and package constraints during integration planning.

Part Context

This component belongs to the BD46xxx series of voltage detectors designed for general-purpose electronic applications. It serves as a replacement for older discrete supervision solutions, offering integrated timing and reset functions in a compact surface-mount package suitable for modern PCB layouts.

Replacement Considerations

The BD5234G-1 is listed as a recommended replacement with similar package dimensions but offers adjustable delay timing rather than fixed delay. Verify pinout compatibility and electrical parameter alignment before substitution.
