BD5335G-TR

Overview

The BD5335G-TR is a voltage detector IC from ROHM Semiconductor, designed for monitoring power supply voltages. It features an adjustable delay time controlled by an external capacitor and provides a CMOS output. The typical under-voltage detection voltage is 3.5V with a precision of ±1%. The reset active voltage range spans from 0.95V to 10V. The device operates within a temperature range of -40°C to 105°C and consumes approximately 0.85μA in both ON and OFF states at VDET=4.8V. It is housed in an SSOP5 package.

Feature Summary

• Adjustable delay timer functionality allows customization of reset timing via an external capacitor.
• CMOS output type ensures compatibility with standard digital logic interfaces.
• High detection accuracy with a typical precision of ±1% for the threshold voltage.

Applications

• Monitoring microprocessor power supply rails
• Battery voltage supervision in portable devices
• Reset signal generation for embedded systems

Procurement Notes

Verify that the BD5335G-TR is not recommended for new designs due to its status as a product for existing customers only. Confirm availability through authorized distributors or legacy stock channels. Ensure the replacement part BD5235G-1TR meets all functional requirements if transitioning to a new design. Check RoHS compliance documentation for environmental regulations.

Selection Notes

Select this component only for maintenance or existing production runs where the BD5335G-TR is already integrated. For new projects, consider the BD5235G-1TR as a recommended alternative with similar pinout and package. Evaluate the need for adjustable delay versus fixed delay options. Assess current consumption requirements against the 0.85μA specification.

Part Context

The BD5335G-TR belongs to the BD53xx series of voltage detectors from ROHM Semiconductor. This series is characterized by high accuracy and low current consumption. The device is specifically identified as a supervisor circuit with a 3.5V detection threshold. It is part of a broader family of PMIC solutions focused on power management and system reliability.

Replacement Considerations

The BD5235G-1TR is a confirmed substitute with the same pinout and package (SSOP5). It offers similar functionality but features an open-drain output instead of CMOS. Verify interface compatibility before substitution.

FAQ

What determines the reset delay time for the BD5335G-TR?

The reset delay time is adjustable and determined by the value of an external capacitor connected to the delay control pin.

Is the BD5335G-TR suitable for automotive applications?

No, the BD5335G-TR is not designated for automotive use according to official specifications.
