BD5252G-TR

Overview

The BD5252G-TR is a voltage detector IC from ROHM Semiconductor, designed for under-voltage detection with an adjustable delay time. It features a typical detection voltage of 5.2V with ±1% precision and an open-drain output type. The reset active state is low, and the device operates within a reset active voltage range of 0.95 to 10V. It consumes 0.85μA in both on and off states at Vdet=4.8V. The component is housed in an SSOP-5 package and supports RoHS compliance.

Feature Summary

• Adjustable delay timer functionality allows customization of reset timing via external components.
• High precision under-voltage detection ensures reliable monitoring of power supply levels.
• Low current consumption design minimizes power usage during operation.

Applications

• Processor supervisor circuits requiring precise voltage monitoring
• Battery-powered devices needing efficient power management
• Automotive electronic systems with strict reliability standards

Procurement Notes

Verify the specific ordering suffix and packaging details when sourcing. Confirm RoHS compliance status and check for any end-of-life notices or last-time-buy recommendations directly from the manufacturer. Ensure the selected variant matches the required detection voltage and package type for your application design.

Selection Notes

Select this component for applications requiring a 5.2V threshold with adjustable delay. Consider the SSOP-5 package size and open-drain output characteristics. Evaluate the low current consumption against system power budgets. Verify compatibility with the operating temperature range and reset active state requirements of the target circuit.

Part Context

The BD5252G-TR belongs to the BD52xx series of voltage detectors from ROHM Semiconductor. This series is known for high accuracy and low current consumption, featuring capacitor-controlled time delays. The BD52xx lineup includes various detection voltages ranging from 2.3V to 6.0V, catering to diverse supervisory circuit needs in portable and automotive electronics.

Replacement Considerations

BD5250G-1 is listed as a similar level part with the same pinout and package. Verify functional equivalence regarding detection voltage (5.0V vs 5.2V) and precision before substitution. Check datasheet specifications for any differences in delay adjustability or current consumption.
