LM3702XCTPX-308/NOPB

Supervisors Overview

The LM3702XCTPX-308/NOPB is a single-channel power supply supervisor manufactured by Texas Instruments. It features a push-pull, totem pole output configuration and monitors one input voltage with a threshold of 3.08 V. The device provides manual reset capability and includes a watchdog timer function. It operates within a supply voltage range up to 5.5 V and offers an accuracy of 0.5%. The component is housed in a 9-pin DSBGA package and supports surface mount installation. It functions reliably across a temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Single-channel voltage monitoring with precise threshold detection
• Push-pull output driver for robust signal integrity
• Integrated watchdog timer for system stability
• Manual reset input for user-controlled recovery

Supervisors Applications

• Networking applications requiring stable signal processing
• Communication signal processing boards
• FPGA-based systems needing reliable power supervision

Supervisors Procurement Notes

Verify the exact datasheet specifications directly from Texas Instruments or authorized distributors before procurement. Confirm that the 308 suffix corresponds to the required 3.08 V threshold for your specific design. Ensure the DSBGA-9 package footprint matches your PCB layout. Check for RoHS compliance status if environmental regulations apply to your project. Validate that the obsolete status does not impact long-term supply chain requirements.

Supervisors Selection Notes

Select this component when a single-channel supervisor with a push-pull output is required rather than open-drain types. The 3.08 V threshold suits applications where the monitored rail operates near this level. Consider the DSBGA-9 package size constraints during PCB design. The integrated watchdog timer eliminates the need for external timing components. Verify compatibility with the system's manual reset logic and operating temperature range.

Supervisors Part Context

This part belongs to the LM370x series of supervisory circuits from Texas Instruments. It is designed for simple reset and power-on reset functions in embedded systems. The series typically offers various thresholds and packages to accommodate different voltage rails and form factors. This specific model focuses on single-channel monitoring with active drive capabilities.

Supervisors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult Texas Instruments application notes or distributor cross-reference tools for potential alternatives. Ensure any replacement maintains the same threshold voltage and output configuration.
