BD5232G-TR

Overview

The BD5232G-TR is a CMOS voltage detector manufactured by ROHM Semiconductor, designed for monitoring power supply voltages. It features an adjustable reset delay timer and operates within a detection voltage range of 0.95 V to 10 V. The typical under-voltage detection threshold is 3.2 V with a precision of ±1%. The device utilizes an open-drain output type and requires no manual reset or watchdog timer functions. It is housed in an SSOP-5 package and supports surface mount installation. The component is rated for operation between -40°C and +105°C.

Feature Summary

• Adjustable reset delay timer functionality allows customization of response timing via external components.
• High accuracy voltage detection with a typical precision of ±1% ensures reliable system supervision.
• Open-drain output configuration provides flexibility for interfacing with various logic levels.

Applications

• Microprocessor system reset circuits
• Power supply monitoring in embedded systems
• Battery-operated device supervision

Procurement Notes

Verify the current lifecycle status before procurement, as this part may be designated as Not Recommended for New Designs (NRND). Confirm that the SSOP-5 package and 3.2 V detection threshold align with existing design requirements. Ensure compatibility with the adjustable delay circuit implementation in your specific application layout.

Selection Notes

Select this component when an adjustable delay time is required for the reset signal generation. Compare against fixed-delay alternatives if timing precision is not critical. Consider the BD5232G-1 as a potential replacement if new designs are initiated, noting differences in operating voltage ranges and current consumption specifications.

Part Context

This component belongs to the BD52 series of CMOS reset ICs from ROHM. These devices are engineered for low current consumption and high accuracy using CMOS processes. The series offers various detection voltages and output types to support diverse supervisory applications in consumer and industrial electronics.

Replacement Considerations

The BD5232G-1 is listed as a recommended alternative with the same pinout and package. Verify functional equivalence regarding the adjustable delay mechanism and electrical characteristics before substitution.
