LM3700XCTP-296/NOPB

Supervisors Overview

The LM3700XCTP-296/NOPB is a single-channel microprocessor supervisor integrated circuit manufactured by Texas Instruments. It operates within an input voltage range of 1.4 V to 5.5 V and provides a reset output with push-pull or open-drain configurations. The device features adjustable reset delay times ranging from 1 ms to 10 s, ensuring reliable system initialization. It supports manual reset functionality via an external button and includes a watchdog timer with selectable timeout periods. Operating temperatures span from -40°C to +85°C, housed in a compact 9-UFBGA package.

Supervisors Feature Summary

• Provides precise power management supervision for microprocessors and complex digital logic circuits
• Features configurable reset delay timers to accommodate various system startup requirements
• Integrates a watchdog timer function to monitor system health and prevent software lockups

Supervisors Applications

• Microprocessor reset monitoring in embedded computing systems
• Power supply supervision for portable electronic devices
• Watchdog timer implementation in industrial control applications

Supervisors Procurement Notes

Verify the specific suffix '296' against the manufacturer's current datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the 9-UFBGA package dimensions align with the PCB footprint. Confirm RoHS compliance status if required by regulatory standards. Cross-reference the revision history for any recent changes to internal circuitry or testing parameters.

Supervisors Selection Notes

Select this component when a single-channel supervisor with adjustable timing is required for low-voltage digital systems. Consider the available reset delay options and watchdog timeout settings to match system stability needs. Evaluate the package size constraints against the available surface-mount options. Compare performance metrics with alternative supervisors if specific voltage thresholds or current capabilities differ from standard requirements.

Supervisors Part Context

This part belongs to the LM3700 series of microprocessor supervisors, designed for reliable operation in digital systems. The series offers flexibility in reset timing and watchdog configuration. The NOPB suffix indicates lead-free packaging compliant with environmental directives. The XCTP variant specifies the particular thermal and mechanical characteristics of the UFBGA package.

Supervisors Replacement Considerations

Direct substitutes may include other LM3700 variants with different suffixes indicating package or temperature variations. Verify functional compatibility regarding reset thresholds and output drive capabilities before substitution. Consult the manufacturer's cross-reference guide for approved alternatives that maintain identical electrical specifications and pin assignments.
