In summary, the hot swap controller consists of a current sense amplifier, a timer circuit, an enable comparator, and a charge Pump FET driver. The hot swap controllers that with power monitoring add a multiplexer to switch between voltage and current measurement, a 12-Bit ADC to read back the data, and an I2C communication bus to allow the data to be read out. These devices are essential for any hot swap design to prevent equipment damage from potential surge transients caused by hot swapping components.
