BD4935G-TR

Overview

The BD4935G-TR is a CMOS voltage detector manufactured by ROHM Semiconductor, designed for monitoring single-input power supply lines. It features a fixed threshold voltage of 3.5 V with a precision of ±1%. The device operates within a supply voltage range of 0.95 V to 10 V and includes a fixed reset delay time of 100 µs. It draws a typical static current of 800 nA at 4.8 V. The component is housed in an SSOP-5 surface-mount package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• CMOS output structure providing low power consumption
• Fixed 100 µs reset delay timer for stable signal generation
• High detection accuracy with ±1% threshold voltage precision

Applications

• Microprocessor system reset circuits
• Portable equipment power management
• Battery-operated device supervision

Procurement Notes

Verify the specific ordering code BD4935G-TR against the latest manufacturer documentation to confirm availability status. This component may be subject to end-of-life or last-time-buy restrictions. Ensure compatibility with existing PCB footprints and thermal requirements before finalizing procurement plans.

Selection Notes

Select this component when a fixed 3.5 V threshold with a 100 µs delay is required. Compare static current specifications against alternative parts if ultra-low power is critical. Verify that the SSOP-5 package dimensions fit the target design constraints and that the CMOS output type matches the downstream logic interface requirements.

Part Context

This part belongs to the BD49 series of standard voltage detectors from ROHM Semiconductor. It serves as a supervisory circuit for maintaining system integrity during power fluctuations. The product line focuses on providing reliable reset signals for digital systems with minimal external component requirements.

Replacement Considerations

BD5235G-1 is listed as a recommended replacement with similar specifications but offers adjustable delay timing.
