BD45375G-TR

Overview

The BD45375G-TR is a voltage detector from the BD45 series manufactured by Rohm Semiconductor. It features a fixed delay time of 50 milliseconds and an open-drain output type with low active reset state. The typical under-voltage detection voltage is 3.7V with a precision of ±1%. The reset active voltage range spans from 0.95V to 10V, and the hysteresis voltage is defined as VDET multiplied by 0.05. It operates within a temperature range of -40°C to 105°C and supports manual reset functionality without a watchdog timer.

Feature Summary

• Provides fixed delay time for stable reset signal generation
• Supports manual reset function for system control
• Features open-drain output compatible with various logic levels

Applications

• Processor supervisor circuits requiring fixed delay
• Battery-powered devices needing under-voltage monitoring
• General electronic systems requiring power-on reset signals

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for last-time-buy notices due to potential end-of-life status. Ensure packaging specifications match requirements for surface-mount assembly processes.

Selection Notes

Select this component when a fixed 50ms delay is required rather than adjustable timing. Compare against similar packages like BD5237G-1 if adjustable delay is acceptable. Consider current consumption differences and reset voltage ranges relative to specific application needs.

Part Context

Part of the BD45 series voltage detectors designed for supervisory applications. Manufactured by Rohm Semiconductor in SSOP-5 package. Similar level replacement available in same package format.

Replacement Considerations

BD5237G-1 serves as a recommended replacement with same SSOP-5 package. Note that BD5237G-1 offers adjustable delay instead of fixed delay.
