LM3704XCMM-308/NOPB

Supervisors Overview

The LM3704XCMM-308/NOPB is a precision voltage supervisor and reset IC manufactured by Texas Instruments. It features a push-pull output stage capable of both sourcing and sinking current, providing robust drive capabilities for downstream logic circuits. The device includes a dedicated power-fail input to monitor supply voltages accurately. Designed for automotive applications, it operates within an extended temperature range from -40°C to +85°C. The component is housed in a compact 10-pin VSSOP package with tape-and-reel packaging for automated assembly.

Supervisors Feature Summary

• Push-pull output stage enables active sourcing and sinking of current for reliable signal integrity
• Dedicated power-fail input allows precise monitoring of supply voltage transitions
• Automotive-grade qualification ensures reliability under harsh environmental conditions
• Low-line output provides additional supervision capability for critical system states

Supervisors Applications

• Processor supervision in automotive electronic control units
• Voltage monitoring for microcontroller reset sequences
• Power-fail detection in industrial embedded systems
• System reset generation for memory backup circuits

Supervisors Procurement Notes

Verify the exact suffix '308' corresponds to the required trip point voltage before ordering. Confirm the 'XMM' package variant matches your PCB footprint requirements. Ensure the 'NOPB' designation aligns with lead-free compliance standards for your manufacturing process. Cross-reference the datasheet revision date to ensure compatibility with latest design guidelines.

Supervisors Selection Notes

Select this component when a push-pull output is required instead of open-drain configurations. Consider the specific 3.08V threshold if it matches the target supply rail tolerance. Evaluate the VSSOP package size constraints against available board space. Verify that the automotive temperature range meets the operational environment specifications.

Supervisors Part Context

This part belongs to the LM370x family of voltage supervisors from Texas Instruments. These devices are designed to provide reliable reset signals and power-fail indications for digital systems. The family offers various fixed thresholds and output configurations to suit different application needs.

Supervisors Replacement Considerations

Check for direct pin-to-pin replacements within the LM370x series with compatible trip points. Verify that alternative supervisors offer similar push-pull output characteristics if current sourcing/sinking is critical.
