BD4835FVE-TR

Overview

The BD4835FVE-TR is a standard voltage detector manufactured by ROHM Semiconductor, designed for monitoring supply voltages in electronic systems. It features an open-drain output type and operates within a reset active voltage range of 0.95 to 10 V. The typical under-voltage detection voltage (Vdet) is 3.5 V with a precision of ±1%. The device includes a fixed reset delay timer and maintains a low circuit current consumption of 0.60 μA at VS=4.8V when active. It is housed in a VSOF-5 package and supports RoHS compliance.

Feature Summary

• CMOS technology ensures ultra-low power consumption suitable for battery-operated applications.
• Open-drain output configuration allows flexible interfacing with various logic families.
• Integrated reset delay timer prevents false triggering during power-up sequences.

Applications

• Portable electronic devices requiring reliable power supervision
• Battery-powered equipment needing low quiescent current monitoring
• General-purpose industrial control systems

Procurement Notes

Verify the specific suffix and packaging details against official ROHM documentation before procurement. Confirm that the VSOF-5 package dimensions match your PCB footprint requirements. Ensure compatibility with your system's voltage range and reset timing needs. Check for any end-of-life notices or obsolescence warnings associated with this part number.

Selection Notes

Select this component when a precise 3.5 V threshold is required with high accuracy. Consider the VSOF-5 package size constraints and the need for an open-drain output. Evaluate if the fixed reset delay meets your system's startup timing specifications compared to adjustable alternatives.
