BD52E33G-TR

Overview

The BD52E33G-TR is a voltage detector manufactured by ROHM Semiconductor, designed for monitoring single-input power supply lines. It features an adjustable reset delay timer and an open-drain output type. The device operates within a detection voltage range of 0.95 V to 10 V, with a typical under-voltage detection threshold of 3.3 V. It offers high precision with a VDET accuracy of ±1%. The component supports a wide operating temperature range from -40°C to +105°C and is housed in an SSOP-5 package.

Feature Summary

• Adjustable reset delay timer allows customization of response timing based on application requirements.
• High detection accuracy ensures reliable voltage monitoring with minimal deviation from the set threshold.
• Low circuit current consumption contributes to energy efficiency in battery-powered or low-power systems.

Applications

• Monitoring power supply voltages in embedded systems
• Providing reset signals for microcontrollers during brown-out events
• Ensuring system stability in portable electronic devices

Procurement Notes

Verify the supply status as Not Recommended for New Designs (NRND). Confirm that the SSOP-5 package and pinout match existing board layouts. Check RoHS compliance documentation if required for specific regulatory standards. Ensure the ordering part number BD52E33G-TR corresponds to the tape-and-reel packaging format.

Selection Notes

Select this component when an adjustable delay time is required alongside high accuracy. Compare the open-drain output capability with CMOS alternatives if drive strength is a constraint. Verify that the 3.3 V detection threshold aligns with the target system's logic levels. Consider the NRND status for long-term production planning.

Part Context

This part belongs to the BD52 series of voltage detectors from ROHM Semiconductor. It is specifically engineered for applications requiring precise voltage supervision with customizable timing characteristics. The series is known for its compact footprint and low power consumption, making it suitable for space-constrained designs.

Replacement Considerations

BD5233G-1 is listed as a similar level replacement with the same pinout and package. Verify compatibility regarding the adjustable delay feature and output type before substitution.
