Overview
The BD5325FVE-TR is a voltage detector IC from ROHM Semiconductor featuring a CMOS output and adjustable delay time. It operates within a supply voltage range of 0.95V to 10V with a typical detection threshold of 2.5V. The device offers high precision accuracy of ±1% and includes hysteresis defined as VDET x 0.05. It functions in an industrial temperature range from -40°C to +105°C, housed in a compact VSOF-5 package.
Feature Summary
- CMOS push-pull output structure for direct logic interfacing
- Adjustable reset delay timer controlled by external capacitor
- High voltage detection accuracy with specified hysteresis
Applications
- Processor supervisor circuits requiring precise power monitoring
- Embedded systems needing programmable reset timing
- Industrial control units operating in wide temperature environments
Procurement Notes
Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and pin alignment against the VSOF-5 specification. Validate datasheet revisions to ensure compatibility with current design requirements before finalizing procurement decisions.
Selection Notes
Select this component when CMOS output drive capability is required alongside adjustable delay functionality. Compare electrical characteristics such as quiescent current and output drive strength against alternatives like the BD5225G-1 series. Ensure the VSOF-5 footprint matches the target PCB layout constraints.
Part Context
This part belongs to the BD53xx series of voltage detectors characterized by low current consumption and capacitor-controlled time delays. It serves as a specialized supervisory circuit within ROHM's PMIC portfolio, designed for applications demanding reliable power management in compact surface-mount configurations.
Replacement Considerations
The BD5225G-1 is documented as a recommended replacement with the same pinout. Verify that the open-drain output of the substitute aligns with the existing pull-up resistor configuration in the target circuit design.
