BD5336FVE-TR

Overview

The BD5336FVE-TR is a CMOS voltage detector manufactured by ROHM Semiconductor, designed for supervisory circuit applications. It features a fixed threshold voltage of 3.6 V with an accuracy of ±1%. The device operates within a supply voltage range of 0.95 V to 10 V and supports a maximum power dissipation of 210 mW. It utilizes a VSOF-5 surface-mount package and offers a programmable reset delay timer without manual reset or watchdog functionality. The component functions across a temperature range of -40°C to +105°C.

Feature Summary

• CMOS output type provides low standby current consumption for battery-powered systems.
• Programmable reset delay timer allows customization of response timing via external components.
• High precision detection accuracy ensures reliable monitoring of supply voltage levels.

Applications

• Portable electronic devices requiring precise power management
• Battery-operated equipment needing under-voltage protection
• Embedded systems utilizing single-input voltage supervision

Procurement Notes

Verify the obsolete status and last-time-buy availability through official ROHM channels before procurement planning. Confirm RoHS compliance details and specific packaging options such as reel or cut tape directly with authorized distributors. Ensure design-in compatibility with existing PCB footprints and thermal requirements given the VSOF-5 package constraints.

Selection Notes

Select this component when a fixed 3.6 V threshold with high accuracy is required for single-channel voltage monitoring. The programmable delay feature distinguishes it from fixed-delay alternatives, offering flexibility in system startup sequences. Consider the VSOF-5 package size for space-constrained designs and verify that the CMOS output interface matches the downstream logic requirements.

Part Context

This part belongs to the BD53xx series of voltage detectors, which are characterized by low power consumption and compact packaging. The BD5336FVE-TR specifically targets applications needing a 3.6 V detection point. It shares pinout compatibility with other variants in the family but differs in threshold voltage and delay configuration capabilities.

Replacement Considerations

BD5236G-1 is listed as a similar level replacement with the same pinout and package, though it features an open-drain output and adjustable delay rather than programmable delay. Verify functional equivalence regarding output type and delay mechanism before substitution.

FAQ

Does the BD5336FVE-TR include a manual reset function?

No, the BD5336FVE-TR does not support manual reset; it relies solely on automatic voltage detection for reset generation.

What is the reset active state for this voltage detector?

The reset signal is active low, indicating that the output goes low when the monitored voltage falls below the threshold.
