LM25061PMMX-2/NOPB

Hot Swap Controllers Overview

The LM25061PMMX-2/NOPB is a positive low voltage power limiting hot swap controller manufactured by Texas Instruments. It operates within a supply voltage range of 2.9 V to 17 V and supports a single channel. The device is housed in a 10-VSSOP package with an exposed pad, suitable for surface-mount installation. It functions across an extended temperature range from -40°C to +85°C. Key programmable features include current limit, fault timeout, and under-voltage lockout (UVLO). The controller draws a typical supply current of 1.6 mA and includes power failure detection capabilities.

Hot Swap Controllers Feature Summary

• Provides intelligent control for high-side N-channel MOSFETs during hot swap events
• Features programmable current limiting and fault timeout protection mechanisms
• Includes input under-voltage lockout with hysteresis for stable operation
• Supports remote on/off control via the enable input pin

Hot Swap Controllers Applications

• Server and storage backplane power management
• Industrial equipment hot swap modules
• Telecommunications infrastructure power distribution
• General purpose board-level hot swap protection

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'X' indicates reel packaging when sourcing. Confirm the '-2' variant matches the required threshold or programming configuration against the official datasheet. Ensure the 10-VSSOP footprint aligns with the PCB layout. Check RoHS compliance status as indicated in the component documentation. Validate the operating temperature range requirements for the target application environment.

Hot Swap Controllers Selection Notes

Select this controller for applications requiring precise power limiting during insertion. Compare the 2.9 V to 17 V input range against system bus voltages. Evaluate the 1.6 mA supply current for low-power standby requirements. Consider the 10-VSSOP package size for space-constrained designs. Verify compatibility with external N-channel MOSFET gate drive requirements.
