32R2412RY-4CVT

Overview

The TPS2412 is a N+1 ORing controller manufactured by Texas Instruments, designed for high-availability power systems. It manages multiple input sources to ensure continuous power delivery. The device operates with an input voltage range of 3V to 16.5V and draws a supply current of 4.25 mA. It features an internal delay time of 130 ns for turn-off operations. The component is available in an 8-TSSOP package with a width of 4.40 mm. It supports N-channel FETs and is rated for operating temperatures between -40°C and 85°C. This controller facilitates redundant power architectures by handling the logic required for seamless source switching.

Feature Summary

• N+1 ORing control architecture for redundant power distribution
• Supports N-channel field-effect transistors for low-loss switching
• Integrated timing control with specified turn-off delay characteristics

Applications

• N+1 redundant power supply systems
• High-availability server and storage power architectures
• Telecommunications equipment requiring uninterrupted power

Procurement Notes

Verify the specific suffix 'RY-4CVT' against official Texas Instruments documentation to confirm package variant and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 8-TSSOP form factor. Cross-reference RoHS compliance status and moisture sensitivity level requirements for your assembly process. Confirm that the N+1 controller logic aligns with your system's redundancy strategy before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring N+1 redundancy for critical loads. Ensure the input voltage range of 3V to 16.5V matches your bus voltage. Verify that the external N-channel MOSFETs selected can handle the expected load current and thermal dissipation. Consider the 8-TSSOP package constraints if space is limited. Evaluate the 130 ns delay parameter against your system's transient response requirements.

Part Context

The TPS2412 belongs to the TPS241x family of ORing controllers from Texas Instruments. It is functionally related to the TPS2413, sharing similar control logic but potentially differing in specific pinouts or feature sets as indicated by datasheet revisions. These devices are part of TI's broader power management portfolio aimed at improving system reliability through active redundancy management.

Replacement Considerations

Check the TPS2413 datasheet for functional equivalence, noting potential differences in pin configuration or specific electrical parameters. Verify if other N+1 ORing controllers from Texas Instruments or alternative manufacturers meet the 3V-16.5V input range and 8-TSSOP package requirement without redesigning the board.
