BU4836FVE-TR

Supervisors Overview

The BU4836FVE-TR is a CMOS voltage detector manufactured by ROHM Semiconductor, designed for monitoring power supply voltages in electronic circuits. It features an open-drain output type and operates within a reset active voltage range of 0.7 V to 7 V. The typical under-voltage detection threshold is set at 3.6 V with a precision of ±1%. The device consumes a circuit current of 0.40 μA when ON (at VDET=4.8V) and 0.55 μA when OFF. It includes hysteresis voltage defined as VDET x 0.05 and supports a low-level output current capability. The component is housed in a VSOF5 package and is rated for operation between -40°C and +125°C.

Supervisors Feature Summary

• CMOS technology ensures ultra-low current consumption for battery-powered applications.
• Open-drain output provides flexibility for interfacing with various logic families.
• Integrated hysteresis prevents output oscillation during voltage transitions near the threshold.

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Microprocessor reset circuits in embedded systems
• Battery-operated equipment needing voltage supervision

Supervisors Procurement Notes

Verify the obsolete status and limited availability before procurement planning. Confirm RoHS compliance details for specific manufacturing dates. Ensure design-in compatibility with the VSOF5 package dimensions and thermal requirements. Check for recommended replacement parts if long-term supply stability is required for production.

Supervisors Selection Notes

Select this component for applications requiring a fixed 3.6 V detection threshold with high accuracy. Consider the low operating current for energy-sensitive designs. Verify that the open-drain output configuration aligns with the system's pull-up requirements. Ensure the operating temperature range meets the environmental conditions of the target application.

Supervisors Part Context

This part belongs to the BU4836 series of standard voltage detectors from ROHM. It is designed to provide reliable reset signals for digital circuits when supply voltage drops below a specified level. The series is known for its compact packaging and low power characteristics, suitable for space-constrained portable electronics.

Supervisors Replacement Considerations

The BD5236G-1TR is listed as a similar specification replacement with comparable voltage detection thresholds and output types. Verify package compatibility and electrical parameter alignment before substitution.
