These devices contain a 0.23Ω current-limited N-channel MOSFET which can operate over an input voltage range of 4.5-20V. Switch control is by a logic input (ON) capable of interfacing directly with low voltage control signals. Each part contains thermal shutdown protection which shuts off the switch to prevent damage to the part when a continuous over-current condition causes excessive heating. Controlled Turn-On 0.4A, 0.8A and Adjustable Current Limit Option Undervoltage Lockout Thermal Shutdown <10µA Shutdown Current Auto Restart Fault Blanking When the switch current reaches the current limit, the part operates in a constant-current mode to prohibit excessive currents from causing damage. For the FPF2500, FPF2501, FPF2503 and FPF2505, if the constant current condition still persists after 5ms, these parts will shut off the switch and, for the FPF2503 and FPF2505, the fault signal pin (FLAGB) will be pulled low. The FPF2500, FPF2503, and FPF2505, have an auto-restart feature which will turn the switch on again after 640ms if the ON pin is still active. The FPF2501 does not have this auto-restart feature so the switch will remain off until the ON pin is cycled. For the FPF2502, FPF2504 and FPF2506, a current limit condition will immediately pull the fault signal pin low and the part will remain in the constant-current mode until the switch current falls below the current limit. For the FPF2500 through FPF2502, the minimum current limit is adjustable from 500mA to 2A. For the FPF2503 and FPF2504 the minimum current is internally fixed at 400mA while that for the FPF2505 and FPF2506 is internally fixed at 800mA.

G 8 www.fairchildsemi.com FPF2500-FPF2506 IntelliMAX™ Advanced Load Management Products Typical Characteristics Current Limiting The FPF2500 - FPF2506 are current limited switches that protect systems and loads which can be damaged or disrupted by the application of high currents. The core of each device is a 0.23Ω N-channel MOSFET and a controller capable of functioning over a wide input operating range of 4.5 V -20 V. The controller protects against system malfunctions through current limiting under-voltage lockout and thermal shutdown. The current limit for FPF2500, FPF2501 and FPF2502 is adjustable from 500mA to 2A through the selection of an external resistor. The FPF2503 and FPF2504 the minimum current is internally fixed at 400 mA while that for the FPF2505 and FPF2506 is internally fixed at 800mA. The current limit ensures that the current through the switch doesn't exceed a maximum value while not limiting at less than a minimum value. For the FPF2500, FPF2501 and FPF2502, the current at which the parts will limit is adjustable through the selection of an external resistor connected to ISET. Information for selecting the resistor is found in the Application Info section. For the FPF2503 and FPF2504 the minimum current is 400mA and the maximum current is 800mA and for the FPF2505FPF2506 the minimum current is 800mA and the maximum current is 1600mA. The FPF2500, FPF2501, FPF2503 and FPF2505 have a blanking time of 5ms, nominally, during which the switch will act as a constant current source. At the end of the blanking time, the switch will be turned-off. For FPF2503 and FPF2505, at the end of the blanking time, the switch will be turned-off and the FLAGB pin will activate to indicate that current limiting has occurred. The FPF2502, FPF2504 and FPF2506 have no current limit blanking period so they will remain in a constant current state. For FPF2504 and FPF2506, immediately upon a current limit condition FLAGB is activated. The FPF2502, FPF2504 and FPF2506 devices will remain in constant current state until the ON pin is cycled or the thermal shutdown turns-off the switch. On/Off Control The ON pin controls the state of the switch. When ON is high, the switch is in the on state. Activating ON continuously holds the switch in the on state so long as there is no fault. For all versions, an under-voltage on VIN or a junction temperature in excess of 140°C overrides the ON control to turn off the switch. In addition, excessive currents will cause the switch to turn off in the FPF2500, FPF2501, FPF2503 and FPF2505. The FPF2500, FPF2503 and FPF2505 have an Auto-Restart feature which will automatically turn the switch on again after 640ms. For the FPF2501, the ON pin must be toggled to turn-on the switch again. The FPF2502, FPF2504 and FPF2506 does not turn off in response to an over current condition but instead remains operating in a constant current mode so long as ON is active and the thermal shutdown or under-voltage lockout have not activated. Under-Voltage Lockout The under-voltage lockout turns-off the switch if the input voltage drops below the under-voltage lockout threshold. With the ON pin active, the input voltage rising above the undervoltage lockout threshold will cause a controlled turn-on of the switch which limits current over-shoots. Thermal Shutdown The thermal shutdown protects the die from internally or externally generated excessive temperatures. During an overtemperature condition the switch is turned-off. The switch automatically turns-on again if the temperature of the die drops below the threshold temperature. FPF2500-FPF2506 Rev.

This resistor is selected by using the following equation, ( 0.485 × I SET ) (1) RSET is in Ohms and ISET is in Amps The following table can also be used to select RSET. A typical application would be the 0.500A current that is required by a single USB port. Using the table below an appropriate selection for the RSET resistor would be 12.4KΩ. This will ensure that the port load could draw 0.525A, but not more than 0.875A. Likewise for a dual port system, an RSET of 34.8KΩ would always deliver at least 1.050A and never more than 1.750A. Input Capacitor To limit the voltage drop on the input supply caused by transient in-rush currents when the switch turns-on into a discharged load capacitor or a short-circuit, a capacitor needs to be placed between VIN and GND. A 0.1µF ceramic capacitor, CIN, must be placed close to the VIN pin. A higher value of CIN can be used to further reduce the voltage drop experienced as the switch is turned on into a large capacitive load. FPF2500-FPF2506 Rev.

This capacitor will prevent parasitic board inductances from forcing VOUT below GND when the switch turns-off. For the FPF2501, FPF2503 and FPF2505, the total output capacitance needs to be kept below a maximum value, COUT(max), to prevent the part from registering an over-current condition and turning off the switch. The maximum output capacitance can be determined from the following formula, For best performance, all traces should be as short as possible. To be most effective, the input and output capacitors should be placed close to the device to minimize the effects that parasitic trace inductances may have on normal and short-circuit operation. Using wide traces for VIN, VOUT and GND will help minimize parasitic electrical effects along with minimizing the case to ambient thermal impedance. I LIM ( min ) × t BLANK ( min ) C OUT ( max ) = ----------------------------------------------------------------V IN (2) Power Dissipation Due to the wide input voltage range that the parts can accept and the high currents at which the current limit can be set, care must be taken to prevent excessive power dissipation in the part from interrupting the switching of power to a load. During normal operation as a switch, the power dissipated in the part will depend upon the level at which the current limit is set. For a 0.5A typical load, the power dissipated will typically be, 2 2 P = ( I LIM ) × R DS = ( 0.5 ) × 0.23 = 58mW (3) This is well within the thermal capability of the package. The maximum allowed setting for the current limit is 2A and this will result in a power dissipation of typically, 2 2 P = ( I LIM ) × R DS = ( 2 ) × 0.23 = 920mW (4) This is beyond the normal thermal capability of the package, but the thermal shutdown within the part will prevent damage by turning off the switch once the maximum junction temperature has been reached. If the part goes into current limit the maximum power dissipation will occur when the output is shorted to ground. For the FPF2500, FPF2503 and FPF2505 the power dissipation will scale by the Auto-Restart Time, tRESTART, and the Over Current Blanking Time, tBLANK, so that the maximum power dissipated is, t BLANK P ( max ) = --------------------------------------------------- × V IN ( max ) × I LIM ( max ) t RESTART + t BLANK 5 (5) = ------------------- × 20 × 2.5 = 388mW 5 + 640 This is more power than the package can dissipate, but the thermal shutdown of the part will activate to protect the part from damage due to excessive heating. The junction temperature will only be able to increase to the thermal shutdown threshold. Once this temperature has been reached, toggling ON will not turn-on the switch until the junction temperature drops. For the FPF2502, FPF2504 and FPF2506, a short on the output will cause the part to operate in a constant current state dissipating a worst case power of, P ( max ) = V IN ( max ) × I LIM ( max ) = 20 × 2.5 = 50W (6) This large amount of power will activate the thermal shutdown and the part will cycle in and out of thermal shutdown so long as the ON pin is active and the short is present.
