APPLICATION NOTE 2913
Hot-Swap Controllers Improve Power-Supply Sequencing

Hot-swap controller ICs implement desired sequence for power-supply voltages.


For many systems, the power-supply voltages must be applied in a definite sequence to prevent circuit damage.
That task was implemented with discrete circuitry in the past, but modern hot-swap-controller ICs offer an
alternative that simplifies the design and increases the performance of power-supply sequencers.


The circuit of Figure 1 provides power-up sequencing for a variety of hot-swap applications, and can be
expanded to control many other supply-
