BD5335FVE-TR

Overview

The BD5335FVE-TR is a voltage detector IC from ROHM Semiconductor featuring a CMOS output and adjustable delay time. It provides an under-voltage detection threshold of 3.5V with ±1% precision. The reset active voltage range spans 0.95V to 10V, supporting low-active reset states. Operating current is 0.85μA at VDET=4.8V. Hysteresis is set at VDET x 0.05. Output currents are 1.2mA (Low) and 5mA (High). The internal delay circuit resistance is 9.0MΩ. It operates within -40°C to 105°C in a VSOF5 package measuring 1.6x1.6mm.

Feature Summary

• CMOS output type for direct logic interface compatibility
• Adjustable delay timer controlled by external capacitor
• High detection accuracy with ±1% precision tolerance
• Wide operating temperature range suitable for industrial environments

Applications

• Processor supervisor circuits requiring precise voltage monitoring
• Battery backup switching systems with defined delay requirements
• Industrial control boards needing reliable power-on reset signals
• Embedded systems utilizing CMOS-compatible reset inputs

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance documentation matches the specific batch. Check datasheet revisions for any updates to electrical characteristics or pinout definitions before integration. Ensure ordering suffixes align with tape-and-reel specifications. Validate supplier credentials against manufacturer lists.

Selection Notes

Choose this part when a CMOS output is required instead of open-drain alternatives. Select based on the fixed 3.5V threshold if no programmable threshold is needed. Consider the adjustable delay feature for noise immunity during power-up. Evaluate the VSOF5 package size constraints against PCB layout requirements. Compare current consumption metrics against other series members for efficiency needs.

Part Context

Part of the BD53xx series of high-precision voltage detectors. Designed for applications requiring accurate supervision without manual reset capabilities. Differentiated from BD52xx series by its CMOS output structure versus open-drain options. Offers comparable functionality to BD5235G-1 but with distinct package and output characteristics.

Replacement Considerations

BD5235G-1 is listed as a recommended replacement with same pinout. Verify package differences between VSOF5 and SSOP5. Check output type changes from CMOS to open drain. Confirm reset active voltage range compatibility. Assess current consumption variations between the two devices.
