BU4335FVE-TR

Overview

The BU4335FVE-TR is a CMOS voltage detector manufactured by ROHM Semiconductor, designed for monitoring single-channel input voltages. It features an adjustable reset delay timer and operates within a supply voltage range of 0.7 V to 7 V. The device provides a low-active reset output with a typical under-voltage detection threshold of 3.5 V and a precision of ±1%. It consumes 0.40 μA in the ON state and 0.55 μA in the OFF state at VDET=4.8 V. The component supports an external delay circuit resistance up to 9.0 MΩ and functions reliably across a temperature range of -40°C to 125°C.

Feature Summary

• Adjustable reset delay timer functionality allows customization of response timing via external components.
• Low power consumption design ensures minimal current draw during active and standby states.
• High accuracy voltage detection with ±1% precision for reliable system supervision.

Applications

• Portable electronic devices requiring low-power voltage supervision
• Battery-operated systems needing precise under-voltage detection
• General-purpose embedded circuits with adjustable reset timing requirements

Procurement Notes

Verify the specific ordering suffix and package type against official documentation before procurement. Confirm that the recommended replacement part BD5235G-1TR meets all electrical and mechanical specifications for your application. Ensure compliance with RoHS standards and check the latest supply status as the original part may be subject to last-time-buy restrictions.

Selection Notes

Select this component when a low-quiescent current voltage detector with adjustable delay is required. Consider the VSOF-5 package size constraints and the need for an external resistor for delay setting. Evaluate the operating voltage range and temperature stability to ensure compatibility with the target system environment and power supply characteristics.

Part Context

This component belongs to the BU42(43)xxFVE series of supervisory circuits from ROHM Semiconductor. It is specifically engineered for applications demanding high accuracy and low power consumption in compact surface-mount packages. The series offers various threshold voltages to suit different logic levels and battery types.

Replacement Considerations

The BD5235G-1TR is listed as a recommended alternative with the same pinout configuration. Verify that the SSOP-5 package dimensions and electrical parameters of the substitute are compatible with the existing PCB layout and circuit design requirements.
