BD46261G-TR

Overview

The BD46261G-TR is a supervisory circuit voltage detector manufactured by ROHM Semiconductor. It features a fixed detection threshold voltage of 2.6V and operates within a supply voltage range of 0.95V to 10V. The device provides a low-active CMOS output with a manual reset function and a fixed delay time of 100ms. It has no adjustable threshold, watchdog timer, or battery backup switch. The component is housed in a 5-pin SSOP package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Provides a fixed under-voltage detection threshold for reliable system monitoring
• Includes a manual reset input for controlled system recovery
• Features a fixed delay timer to prevent false resets during power-up
• Delivers a low-active CMOS output signal compatible with digital logic

Applications

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

Procurement Notes

Verify the specific suffix G-TR against the official datasheet to confirm the SSOP-5 packaging and tape-and-reel delivery format. Ensure the part number matches the exact detection voltage requirements for your design. Confirm RoHS compliance status through the manufacturer's current documentation before procurement.

Selection Notes

Select this component when a fixed 2.6V detection threshold is required without the need for external adjustment. It is suitable for applications needing a simple, low-cost supervisory solution with manual reset capability. Consider the fixed 100ms delay and CMOS output characteristics when interfacing with target microcontrollers or logic gates.

Part Context

This part belongs to the BD46 series of voltage detectors from ROHM Semiconductor. These devices are designed for general-purpose electronic equipment requiring stable power supply monitoring. The series typically offers various fixed detection voltages and packaging options to suit different application constraints.

Replacement Considerations

The BD5226G-1TR is listed as a replacement with the same package type. Note that the replacement features an open-drain output and adjustable delay, which differs from the BD46261G-TR's CMOS output and fixed delay.
