BD4735G-TR

Overview

The BD4735G-TR is a standard voltage detector manufactured by ROHM Semiconductor, designed for monitoring single-channel power supply voltages. It operates within a supply voltage range of 0.85 V to 10 V and features a fixed threshold detection voltage of 3.5 V with ±1% accuracy. The device utilizes an open-collector output type and lacks manual reset or watchdog timer functionalities. It is housed in a compact SSOP-5 surface-mount package and supports operation across a temperature range of -40°C to +75°C.

Feature Summary

• Provides precise voltage supervision with high detection accuracy
• Features low-power consumption suitable for battery-operated systems
• Offers compact surface-mount packaging for space-constrained designs

Applications

• Microprocessor system reset circuits
• Battery-powered device power management
• Portable electronic equipment supervision

Procurement Notes

Verify the component status as this part may be subject to end-of-life restrictions. Confirm that the SSOP-5 package dimensions and pinout align with your PCB footprint requirements. Ensure the operating temperature range meets your specific environmental conditions. Cross-reference the datasheet for any recent design changes or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a fixed 3.5 V threshold is required for single-voltage monitoring. Consider the open-collector output compatibility with your system logic levels. Evaluate the static current consumption against battery life requirements. Verify that the absence of a reset delay timer does not conflict with system startup timing specifications.

Part Context

This component belongs to the BD47xx series of standard voltage detectors from ROHM Semiconductor. It is part of a family of supervisory circuits designed for general-purpose power management applications. The series typically offers various threshold voltages and package options to accommodate different design needs while maintaining consistent performance characteristics.
