BD5233G-DTR

Overview

The BD5233G-DTR is a CMOS voltage detector IC from ROHM Semiconductor, designed for monitoring single-channel power supply voltages. It features a typical threshold voltage of 3.3V with high precision accuracy. The device operates within a supply voltage range of 0.95V to 10V and provides an open-drain output. Key electrical parameters include a reset delay time that is programmable via an external capacitor, ensuring reliable system resets during under-voltage conditions. It supports a wide operating temperature range from -40°C to +105°C.

Feature Summary

• Adjustable reset delay time controlled by an external capacitor
• High-precision voltage detection with low current consumption
• Open-drain output configuration for flexible interfacing

Applications

• Consumer electronics power supply monitoring
• Automotive xEV systems
• General-purpose voltage supervision in embedded systems

Procurement Notes

Verify the specific suffix 'DTR' indicates cut-tape or reel packaging options as per distributor listings. Confirm RoHS compliance status through official datasheets. Check for end-of-life notifications or recommended replacement parts if sourcing for new designs. Ensure compatibility with required thermal management specifications for the target application environment.

Selection Notes

Select this component when a precise 3.3V threshold is required with customizable reset timing. The open-drain output allows for easy integration with various logic levels. Consider the external capacitor requirement for delay setting when designing the PCB layout. Verify that the operating temperature range meets the environmental constraints of the final product.

Part Context

This part belongs to the BD52xx series of voltage detectors, which are known for their low power consumption and high accuracy. The BD5233G variant specifically targets applications needing a 3.3V detection level. The DTR suffix typically denotes tape-and-reel packaging suitable for automated assembly processes.

Replacement Considerations

The BD5233G-TR is a similar pinout alternative. The BU4233FVE is listed as a similar level part with the same pinout but different package (VSOF5 vs SSOP5). Verify functional equivalence before substitution.
