Texas Instruments LM25069 Positive Low Voltage Power Limiting Hot Swap Controller LM25069PMMX-1/NOPB

The LM25069PMMX-1/NOPB is a positive low voltage power limiting hot swap controller designed by Texas Instruments. It operates within a voltage range of +2.9V to +17V and is suitable for applications such as server backplane systems and base station power distribution. The device features in-rush current limiting to ensure safe board insertion into live power sources, along with programmable maximum power dissipation in the external pass device. Key functionalities include adjustable current limits, under-voltage and over-voltage lockout settings, and a circuit breaker function for severe over-current events. The LM25069 also incorporates an internal high-side charge pump and gate driver for an external N-channel MOSFET, enhancing its operational flexibility. The device is packaged in a 10-pin VSSOP format and is rated for operation over a temperature range of -40¬8C to +85¬8C. Engineers may find this product beneficial for applications requiring robust power management and protection during hot swapping of circuit cards.
