DESCRIPTION
The TPS2310 and TPS2311 are dual-channel hotswap controllers that use external N-channel
MOSFETs as high-side switches in power applications. Features of these devices, such as overcurrent protection (OCP), inrush current control, output-power status reporting, and the ability to discriminate between load transients and faults, are critical requirements for hot-swap applications.
