BD52E53G-TR

Overview

The BD52E53G-TR is a voltage detector IC from the BD52Exxx-M series by ROHM Semiconductor. It features an N-channel open drain output and supports detection voltages from 2.3V to 6.0V in 0.1V steps, with a typical threshold of 5.3V. The device offers high accuracy of ±1.0% and ultra-low current consumption of 0.85µA (typical). Reset delay time is adjustable via an external capacitor. It operates within a supply voltage range of 0.95V to 10V and functions across temperatures from -40°C to +105°C.

Feature Summary

• Delay time controlled by external capacitor
• Ultra-low current consumption
• High accuracy detection voltage

Applications

• Circuits using microcontrollers or logic circuits that require a reset
• Automotive accessories power management

Procurement Notes

Verify the component status as Not Recommended for New Designs (NRND) before procurement. Confirm availability through authorized distributors as production may be limited. Ensure the SSOP-5 package and taping specifications match your assembly requirements. Check RoHS compliance documentation for regulatory adherence.

Selection Notes

Select this component for applications requiring precise voltage monitoring with customizable reset timing. The open-drain output suits interfacing with various logic families. Consider the low quiescent current for battery-operated systems. Verify that the required detection voltage falls within the available 0.1V increment range.

Part Context

This part belongs to the BD52Exxx-M series of CMOS Voltage Detector ICs. It is designed for highly accurate supervision of power supplies in embedded systems. The series includes variants with different detection thresholds and output types, such as the BD53Exxx series which features CMOS outputs instead of open drain.

Replacement Considerations

BD5250G-1TR is listed as a similar level replacement with the same pinout and package.
