M51943BML#TF0J

Supervisors Overview

The M51943BML#TF0J is a voltage detecting and system resetting integrated circuit manufactured by Renesas Electronics. It belongs to the M51943B series, which provides fixed detection voltages for power supply monitoring. The device operates within a single channel configuration with a fixed detection voltage of +4.25V. It is housed in a SOT-89 package, specifically designated as PSSO3 or SC-62, featuring three pins. This component functions as a power supply support circuit designed to ensure system stability by monitoring supply levels.

Supervisors Feature Summary

• Provides fixed voltage detection at +4.25V for continuous power supply monitoring
• Integrates system resetting functionality to maintain operational integrity during voltage fluctuations
• Utilizes a compact three-pin SOT-89 (PSSO3/SC-62) surface-mount package for space-efficient board layouts

Supervisors Applications

• Power supply support circuits requiring fixed threshold monitoring
• System resetting applications in embedded electronics
• Voltage detection modules in consumer and industrial devices

Supervisors Procurement Notes

Verify the specific suffix #TF0J against official Renesas documentation to confirm tape-and-reel packaging specifications and moisture sensitivity level. Ensure compatibility with the required operating temperature range and confirm that the fixed 4.25V detection voltage aligns with the target circuit design requirements before procurement.

Supervisors Selection Notes

Select this component when a fixed 4.25V detection threshold is required for system reset logic. The SOT-89 package offers a balance between thermal performance and small footprint. Consider the M51943B series variants if different detection voltages or alternative packages such as SIP-5 or TO-92L are needed for the application.

Supervisors Part Context

The M51943B series comprises voltage detecting and system resetting ICs originally developed by Mitsubishi Electric and now maintained by Renesas Electronics. These components are designed for reliable power management in various electronic systems. The ML suffix indicates the SOT-89 package variant, distinguishing it from other form factors like the SL (TO-92L) or L (SIP-5) versions within the same functional family.

Supervisors Replacement Considerations

Direct substitutes include other M51943BML variants with identical electrical characteristics but potentially different packaging suffixes or manufacturing origins. Verify pinout compatibility and detection voltage tolerance when considering cross-manufacturer alternatives.
