Overview
The BD5327FVE-TR is a voltage detector IC from ROHM Semiconductor featuring an adjustable delay timer and CMOS output. It operates within a supply voltage range of 0.95V to 10V with a typical under-voltage detection threshold of 2.7V and ±1% precision. The device draws 0.85μA at VDET=4.8V, supports a reset active state of Low, and includes hysteresis defined as VDET x 0.05. It functions in the -40°C to +105°C temperature range using a VSOF5 package (1.6x1.6mm).
Feature Summary
- Features an adjustable delay timer for customizable reset timing.
- Provides high-precision voltage monitoring with ±1% accuracy.
- Utilizes a compact VSOF5 surface-mount package.
Applications
- Portable electronic devices requiring low power supervision
- Battery-powered systems needing precise voltage thresholds
- Embedded circuits with programmable reset delays
Procurement Notes
Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance and package integrity upon receipt. Validate datasheet revisions against specific manufacturing batches to ensure parameter consistency. Check for obsolescence notices before finalizing procurement plans.
Selection Notes
Select this component when adjustable delay functionality is required alongside standard voltage detection. Compare current consumption and package dimensions against alternatives like the BD5227G-1 if pinout compatibility is not critical. Ensure the 10V maximum operating voltage aligns with system supply rails.
Part Context
Part of the BD53xx series supervisory circuits designed for portable applications. Manufactured by ROHM Semiconductor, it belongs to the PMIC category. The FVE suffix indicates the VSOF5 package type, distinguishing it from SSOP variants in the same family.
Replacement Considerations
BD5227G-1TR is documented as a recommended replacement with the same pinout. Verify electrical differences such as output type (Open drain vs CMOS) and operating voltage range before substitution.
FAQ
What is the typical under-voltage detection voltage?
