ap2141/ ap2151 document number: ds31562 rev. 7 - 2 11 of 17 www.diodes.com march 2013 ? diodes incorporated ap2141/ ap2151 application information (cont.) thermal protection thermal protection prevents the ic from damage when heavy-overl oad or short-circuit faults are present for extended periods of time. the ap2141/ap2151 implements a thermal sensing to monitor the operati ng junction temperature of the power distribution switch. once the die temperature rises to approximately 140c due to excessive power di ssipation in an over-current or short-circuit condition the i nternal thermal sense circuitry turns the power switch off, thus preventing the power sw itch from damage. hysteresis is built into the thermal sense circuit allowing the device to cool down approximately 25c before the switch turns back on. the switch continues to cycle in this manner until the load fault or input power is removed. the flg open-drain output is asserted when an over-temperature shutdown or over-current occurs with 7-ms degl itch. under-voltage lockout (uvlo) under-voltage lockout function (uvl o) keeps the internal power switch from bei ng turned on until the power supply has reached a t least 1.9v, even if the switch is enabled. whenever the input voltage falls below approximately 1.9v, the power switch is quickly turned off. th is facilitates the design of hot-insertion systems where it is not possible to turn off the power switch before input power is removed. host/self-powered hubs hosts and self-powered hubs (sph) have a local power supply that powers the embedded functions and the downstream ports (see fi gure 2). this power supply must provide from 5.25v to 4.75v to the board side of the downstream connection under both full-load and no-load c onditions. hosts and sphs are required to have current-limit protection and must repor t over-current conditions to the usb controller. typical s phs are desktop pcs, monitors, printers, and stand-alone hubs. figure 2. typical one-port usb host / self-powered hub generic hot-plug applications in many applications it may be necessary to remove modules or pc boards while the main unit is still operating. these are consi dered hot-plug applications. such implementations require th e control of current surges seen by the main power supply and the card being inser ted. the most effective way to control these surges is to limit and slowly ramp the current and voltage being applied to the card, similar to the way in which a power supply normally turns on. due to the controlled rise times and fall times of the ap2141/ap2151, these devices can be used to provide a softer start-up to devices being hot-plugged into a powered system . the uvlo feature of the ap2141/ap2151 also ensures that the switch is off after the card has been removed, and that the switch is off during the next insertion. by placing the ap2141/ap2151 between the v cc input and the rest of the circuitry, the input po wer reaches these devices first after insertion. the typical rise time of the switch is approximately 1ms, providi ng a slow voltage ramp at the output of the device. this implement ation controls system surge current and provides a hot-p lugging mechanism for any device.
