LM25061 Datasheet Positive Low Voltage Power Limiting Hot-swap Controller

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM25061 Positive Low Voltage Power Limiting Hot Swap Controller ..

General Description

The LM25061 positive hot swap controller provides intelligent control of the power supply voltage to the load during insertion and removal of circuit cards from a live system backplane or other "hot" power sources.

The LM25061 provides in-rush current control to limit system voltage droop and transients.

The current limit and power dissipation in the external series pass N-Channel MOSFET are programmable, ensuring operation within the Safe Operating Area (SOA).

Key Features

  • Operating range: +2.9V to +17V.
  • In-rush current limit for safe board insertion into live power.
  • sources Programmable maximum power dissipation in the external pass device Adjustable current limit Circuit breaker function for severe over-current events Internal high side charge pump and gate driver for external N-channel MOSFET Adjustable under-voltage lockout (UVLO) and hysteresis Adjustable output voltage monitoring and hyste.
