BU4336G-TR

Overview

The BU4336G-TR is a CMOS voltage detector manufactured by ROHM Semiconductor, designed for supervisory circuit applications. It features an adjustable reset delay time and operates within a supply voltage range of 0.7 V to 7 V. The device provides a detection threshold voltage of 3.6 V with a precision of ±1%. It utilizes an open-drain output type and does not include manual reset or watchdog timer functions. The component is housed in an SSOP-5 package and supports operation temperatures from -40°C to +125°C.

Feature Summary

• Features an adjustable reset delay timer for customized timing control
• Provides high-precision voltage detection with ±1% accuracy
• Operates with low power consumption suitable for battery-powered systems

Applications

• Portable electronic devices requiring low voltage monitoring
• Battery-operated equipment needing under-voltage protection
• General-purpose supervisory circuits in consumer electronics

Procurement Notes

Verify the current lifecycle status before procurement, as this component may be marked as Not Recommended for New Designs (NRND). Confirm that the SSOP-5 package and specific 3.6 V threshold align with your design requirements. Ensure compatibility with existing PCB footprints if replacing older inventory. Check for alternative recommended parts if new designs are required.

Selection Notes

Select this component when a precise 3.6 V detection threshold is required with adjustable delay capabilities. The open-drain output allows for flexible interfacing with various logic levels. Consider the wide operating temperature range for industrial or automotive environments where standard commercial grades may fail. Verify that the single-input configuration meets the system's monitoring needs without unnecessary complexity.

Part Context

This part belongs to the BU43xxG series of voltage detectors from ROHM Semiconductor. It is specifically engineered for low-voltage detection in compact surface-mount packages. The series is known for integrating essential supervisory functions into a minimal footprint, making it suitable for space-constrained portable applications.

Replacement Considerations

The BD5236G-1 is listed as a replacement with the same pinout and package. Verify electrical parameter compatibility, particularly regarding output drive strength and hysteresis characteristics, before substitution.
