LM3704XCMM-263/NOPB

Supervisors Overview

The LM3704XCMM-263/NOPB is a single-channel voltage supervisor integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 1.5 V to 5.5 V and features a fixed reset threshold voltage of 2.63 V. The device provides a push-pull or open-drain active-low reset output and includes an external input for power-fail detection. It is housed in a 10-pin VSSOP package and supports industrial temperature ranges.

Supervisors Feature Summary

• Provides precise voltage monitoring with a fixed 2.63 V threshold
• Supports configurable reset output polarity via external pin
• Integrates power-fail detection capability through dedicated input
• Operates efficiently at low supply voltages down to 1.5 V

Supervisors Applications

• Microprocessor system supervision
• Battery-powered equipment voltage monitoring
• Industrial control board power management
• Communication module reset generation

Supervisors Procurement Notes

Verify the specific suffix '263' confirms the 2.63 V threshold requirement, as other suffixes indicate different trip points. Ensure the 'NOPB' designation aligns with current RoHS compliance standards. Confirm the 10-VSSOP package type matches your PCB footprint design. Cross-reference the manufacturer's latest datasheet revision to ensure compatibility with your system's timing requirements.

Supervisors Selection Notes

Select this component when a fixed 2.63 V reset threshold is required for low-voltage logic systems. Consider the LM3704 series if power-fail signaling is needed alongside standard reset functions. Evaluate the VSSOP package size against available board space constraints. Compare alternative supervisors if adjustable thresholds or multiple channels are necessary for the application.

Supervisors Part Context

This part belongs to the LM3704 family of voltage supervisors from Texas Instruments. These devices are designed to monitor supply voltages and generate reset signals for digital circuits. The family offers various threshold options distinguished by numeric suffixes, allowing designers to match specific voltage levels without external resistors.

Supervisors Replacement Considerations

Compatible substitutes include LM3704XCMM-285/NOPB (2.85 V threshold) and LM3704XCMM-308/NOPB (3.08 V threshold). Verify that the replacement maintains the same 10-VSSOP package and electrical characteristics suitable for the target voltage level.
