BD5351G-TR

Overview

The BD5351G-TR is a voltage detector manufactured by Rohm Semiconductor, designed for monitoring power supply levels with an adjustable delay time feature. It operates within a reset active voltage range of 0.95 to 10 V and features a typical under-voltage detection voltage of 5.1 V with ±1% precision. The device consumes 0.85 μA in both ON and OFF states at VDET=4.8V. It utilizes a CMOS output type with a low reset active state and lacks manual reset or watchdog timer functions. The component is housed in an SSOP5 package, supports RoHS compliance, and has a recommended replacement part number of BD5250G-1TR.

Feature Summary

• Adjustable delay timer functionality for customized reset timing
• CMOS output interface with low active reset state
• High precision under-voltage detection capability

Applications

• Power supply supervision in electronic systems
• Reset signal generation for microcontrollers
• Voltage monitoring in portable devices

Procurement Notes

Verify the current supply status as the BD5351G is indicated as being in the process of manufacturing suspension. Confirm compatibility with the recommended substitute BD5250G-1TR if sourcing new units. Ensure the ordering part number matches the required tape and reel quantity specifications for production integration.

Selection Notes

Select this component when an adjustable delay timer is required alongside precise voltage detection. Consider the SSOP5 package size for space-constrained designs. Evaluate the BD5250G-1TR as a potential alternative if availability is constrained, noting differences in output type and operating temperature range.

Part Context

This component belongs to the BD53 series of voltage detectors from Rohm Semiconductor. It is categorized under supervisory circuits and power management ICs. The specific model BD5351G-TR indicates the tape and reel packaging format, suitable for automated assembly processes in manufacturing environments.

Replacement Considerations

The BD5250G-1TR is listed as a similar level replacement with the same pinout. Verify that the open-drain output of the substitute is compatible with the existing circuit design compared to the CMOS output of the original part.
