BD5345G-TR

Overview

The BD5345G-TR is a voltage detector supervisory circuit manufactured by ROHM Semiconductor, designed for monitoring single-channel power supply voltages. It features an adjustable delay timer and operates within a reset active voltage range of 0.95 V to 10 V. The device provides a CMOS output type with a low-active reset state and includes manual reset functionality. It supports a maximum power supply voltage of 10 V and maintains a detection precision of ±1%. The component is housed in an SSOP5 package and is rated for operation between -40°C and +105°C.

Feature Summary

• Integrates an adjustable delay timer circuit for customizable reset timing without external capacitors
• Utilizes CMOS process technology to achieve low current consumption and high detection accuracy
• Provides flexible reset active voltage range supporting various system power levels

Applications

• Embedded systems requiring precise power supply supervision
• Microcontroller reset circuits with configurable delay requirements
• Industrial control equipment operating in extended temperature environments

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolete status. Confirm RoHS compliance documentation matches the specific batch. Ensure handling procedures account for surface-mount packaging specifications. Validate that the SSOP5 footprint aligns with existing PCB designs before procurement.

Selection Notes

Select this component when adjustable delay timing is required for reset sequences. Consider the CMOS output capability for direct logic interfacing. Evaluate the wide reset active voltage range against system power rail variations. Assess thermal performance within the specified operating temperature limits for the target application environment.

Part Context

This part belongs to the BD53 series of voltage detectors from ROHM Semiconductor. It is positioned as a legacy product not recommended for new designs, with the BD5245G-1 identified as a recommended replacement offering similar pinout and package compatibility while maintaining updated manufacturing support.

Replacement Considerations

The BD5245G-1 is documented as a recommended replacement with the same SSOP5 package and pinout. Verify electrical parameter compatibility, particularly regarding output type differences (Open Drain vs CMOS) and reset active voltage ranges before substitution.
