BD52E34G-MTR

Overview

The BD52E34G-MTR is a single-channel voltage detector manufactured by Rohm Semiconductor, designed for automotive applications. It features an adjustable reset delay timer controlled by an external capacitor and operates within a supply voltage range of 0.95 V to 10 V. The typical under-voltage detection threshold is set at 3.4 V with a precision of ±1%. The device utilizes an open-drain output type with a low-active reset state. It is housed in a compact SSOP-5 package and supports a wide operating temperature range from -40°C to 105°C.

Feature Summary

• Adjustable reset delay time controlled via an external capacitor connected to the device.

Applications

• Automotive electronic system monitoring
• Voltage supervision for microcontrollers
• Power management circuit protection

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for functional safety support documentation. Ensure the specific ordering suffix matches the required tape-and-reel packaging configuration. Validate that the part meets AEC-Q100 automotive grade standards before integration into final assemblies.

Selection Notes

Select this component when a precise 3.4 V detection threshold is required for automotive power rails. The adjustable delay feature allows customization of reset timing based on external capacitance values. Consider the open-drain output capability for interfacing with various logic levels within the 0.95 V to 10 V operating range.

Part Context

This part belongs to the BD52E series of voltage detectors specifically engineered for automotive environments. It shares pinout compatibility with other variants in the family but offers distinct threshold characteristics. The series emphasizes reliability and functional safety support for critical vehicle systems.

Replacement Considerations

BD5234G-1 is listed as a recommended replacement with the same pinout and package configuration.
