TPS2420RSAT, Контроллер горячей замены, 3В до 20В питание, QFN-16

The TPS2420RSAT is an integrated FET Hot Swap Controller with dual fault threshold, IMON and PG provides highly integrated load protection for applications up to 20V. The maximum UV turn-on threshold of 2.9V makes the TPS2420 well suited to standard bus voltages as low as 3.3V. The TPS2420 device protects loads, minimizes inrush current and safely shuts down in the event of a fault. The programmable fault current threshold starts the fault timer while allowing the current to pass to the load uninhibited. The programmable current limit threshold sets the maximum current allowed into the load, for both inrush and severe load faults. Both events use the programmable timer which inhibits all current to the load when it expires. The dual protection thresholds are useful in applications such as disk drives. The start-up and seek currents are typically higher than the nominal current and during this time the load needs a low impedance path to deliver the power.
