BD52E34G-TR

Overview

The BD52E34G-TR is a single-channel voltage detector manufactured by ROHM Semiconductor, designed for monitoring power supply integrity in electronic circuits. It features an adjustable reset delay timer and operates within a supply voltage range of 0.95 V to 10 V. The device provides a typical under-voltage detection threshold of 3.4 V with a precision of ±1%. It utilizes an open-drain output type and supports a reset active state that is low. The component is housed in a compact SSOP-5 package and is rated for operation across a temperature range from -40°C to +105°C.

Feature Summary

• Features an adjustable reset delay timer for customizable timing control.
• Provides high-precision voltage detection with ±1% accuracy at the threshold.
• Utilizes an open-drain output configuration for flexible interfacing.

Applications

• Monitoring power supply voltages in embedded systems
• Providing reset signals for microcontrollers and logic circuits
• Ensuring system stability during power-up and power-down sequences

Procurement Notes

Verify the specific suffix and packaging details against official datasheets before ordering, as availability may vary. Confirm that the application environment falls within the specified operating temperature range of -40°C to +105°C. Ensure compatibility with the 0.95 V to 10 V supply voltage window. Check for any RoHS compliance documentation required for your region. Validate that the open-drain output interface matches your circuit design requirements.

Selection Notes

Select this component when a precise 3.4 V detection threshold is required with adjustable delay capabilities. Consider the open-drain output if level shifting or wired-OR configurations are needed. Evaluate the SSOP-5 package size constraints against available board space. Compare the ±1% precision against other options if tighter tolerances are necessary. Assess the wide operating voltage range suitability for varying supply conditions.

Part Context

This part belongs to the BD52 series of voltage detectors from ROHM Semiconductor, which focuses on supervisory circuits for power management. The BD52E34G-TR specifically offers adjustable delay features, distinguishing it from fixed-delay variants. It is part of a broader family of components designed for reliable power monitoring in consumer and industrial electronics.

Replacement Considerations

BD5234G-1TR is listed as a recommended replacement with the same pinout and package. Verify electrical parameter equivalence, particularly regarding the open-drain output and adjustable delay functionality, before substituting.
