BD5329G-TR

Overview

The BD5329G-TR is a voltage detector from ROHM Semiconductor, designed for monitoring single-input power supplies. It features a typical threshold voltage of 2.9 V with a precision of ±1%. The device operates within a reset active voltage range of 0.95 V to 10 V and utilizes a CMOS output type. Key functional attributes include an adjustable delay timer and a low reset active state. It lacks manual reset, watchdog timer, and battery backup switch capabilities. The component supports surface mount installation in an SSOP-5 package and is rated for operation between -40°C and +105°C.

Feature Summary

• Adjustable delay timer functionality
• CMOS output interface
• Single input voltage monitoring

Applications

• Power supply supervision
• Microprocessor reset circuits
• Battery voltage monitoring

Procurement Notes

Verify the current lifecycle status before procurement, as this part may be marked as Not Recommended for New Designs (NRND) or End-of-Life. Confirm availability through authorized distributors, noting that standard factory packaging quantities typically apply. Ensure the specific ordering suffix matches the required tape-and-reel configuration for automated assembly processes.

Selection Notes

Select this component when a fixed 2.9 V detection threshold with adjustable timing is required. Compare against the BD5229G-1 if open-drain output or different operating temperature ranges are needed. Verify that the SSOP-5 footprint aligns with the PCB design constraints and that the CMOS output drive capability meets the load requirements of the downstream circuitry.

Part Context

This component belongs to the BD53 series of supervisory circuits manufactured by ROHM Semiconductor. It is categorized under PMIC - Power Management ICs and specifically functions as a simple reset/voltage detector. The series is designed for general-purpose electronic applications requiring reliable power management and system reset control.

Replacement Considerations

The BD5229G-1 is listed as a similar level replacement with the same pinout and package. Note differences in output type (open drain vs. CMOS) and operating temperature range when substituting.
