BD5250G-TR

Overview

The BD5250G-TR is a CMOS voltage detector manufactured by ROHM Semiconductor, designed for monitoring power supply voltages in electronic circuits. It features an adjustable reset delay timer and operates with a typical under-voltage detection voltage of 5.0V. The device provides high precision with a Vdet accuracy of ±0.9% and supports a reset active voltage range from 0.8V to 6V. It utilizes an open-drain output type and maintains low circuit current consumption of 0.23μA (on) and 0.27μA (off). The component is housed in an SSOP-5 package and complies with RoHS standards.

Feature Summary

• Adjustable reset delay timer functionality allows customization of response timing.
• High precision voltage detection ensures accurate monitoring with minimal error margins.
• Ultra-low current consumption supports energy-efficient system designs.

Applications

• Power supply monitoring in portable electronic devices
• Voltage supervision in embedded systems requiring precise threshold detection
• Reset signal generation for microcontrollers during power-up or brown-out events

Procurement Notes

Verify the specific ordering suffix and package variant when sourcing replacements, as availability may vary. Confirm RoHS compliance status and check for any end-of-life notifications or last-time-buy recommendations from the manufacturer. Ensure the selected substitute matches the original pinout and electrical specifications to maintain circuit integrity without redesign.

Selection Notes

Select this component when a fixed 5.0V threshold with adjustable delay is required. Consider the SSOP-5 package size for space-constrained layouts. Evaluate the open-drain output compatibility with downstream logic levels. Compare current consumption requirements against other family members if lower standby current is critical for battery-operated applications.

Part Context

This part belongs to the BD52 series of voltage detectors from ROHM Semiconductor. It is distinct from similar models like the BD5255G by its specific 5.0V detection threshold. The series is characterized by nano-energy consumption capabilities and flexible delay settings, catering to modern low-power design trends in consumer and industrial electronics.

Replacement Considerations

BD5250G-1TR is listed as a similar level replacement with the same pinout and package. Verify that the -1 suffix does not alter functional parameters before substitution.
