LM3724IM5X-2.32/NOPB

Supervisors Overview

The LM3724IM5X-2.32/NOPB is a voltage supervisory circuit manufactured by Texas Instruments, designed for monitoring single power supply rails. It operates within an industrial temperature range of -40°C to +85°C and utilizes a SOT-23-5 surface-mount package. The device features a fixed threshold voltage of 2.32 V, ensuring precise detection of under-voltage conditions. It includes a manual reset input capability and provides an open-drain output for system control. The component is part of the LM3724 series, offering low quiescent current characteristics suitable for battery-powered applications.

Supervisors Feature Summary

• Provides manual reset functionality via dedicated input pin
• Features ultra-low quiescent current consumption for energy efficiency
• Includes time-delay function to prevent false triggering during power transitions

Supervisors Applications

• Microprocessor reset circuits in embedded systems
• Battery-powered portable devices requiring low standby current
• Industrial control systems with strict voltage monitoring requirements

Supervisors Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence as per Texas Instruments standards. Confirm the 'X' designation corresponds to tape-and-reel packaging if bulk procurement is intended. Ensure the operating temperature range meets your application's environmental specifications. Cross-reference the marking code R53B on the physical component to validate authenticity against official TI documentation.

Supervisors Selection Notes

Select this component when a single-channel supervisor with a 2.32 V threshold is required. Consider the SOT-23-5 package size constraints for PCB layout. Evaluate the need for manual reset inputs versus automatic power-on reset only. Compare quiescent current specifications against other supervisors in the LM3724 family if lower power consumption is critical for the target application.

Supervisors Part Context

This part belongs to the LM372x series of microprocessor reset circuits from Texas Instruments. The series typically offers various threshold voltages and package options to suit different design needs. The LM3724 variant specifically focuses on single-supply monitoring with integrated delay functions. It complements other PMIC solutions by providing reliable voltage supervision without complex configuration requirements.

Supervisors Replacement Considerations

Check for direct equivalents within the LM3724 family with different threshold voltages if system voltage levels have changed. Verify pin compatibility with alternative supervisors from other manufacturers before substitution. Ensure that any replacement maintains the same open-drain output structure and manual reset capability.
