The device contains a 0.12 W current−limited P−channel MOSFET which can operate over an input voltage range of 1.8−5.5 V. Internally, current is prevented from flowing when the MOSFET is off and the output voltage is higher than the input voltage. Switch control is by a logic input (ON) capable of interfacing directly with low−voltage control signals. The FPF2165R contains thermal shutdown protection, which shuts off the switch to prevent damage to the part when a continuous over−current condition causes excessive heating. When the switch current reaches the current limit, the part operates in a Constant−Current (CC) mode to prohibit excessive currents from causing damage. The FPF2165R does not turn off after a current limit fault; it remains in the constant current mode indefinitely. The minimum current limit is 150 mA. The FPF2165R is available in a space−saving 6−pin 2 mm x 2 mm Molded Leadless Package (MLP).

Short circuit condition is detected by observing the output voltage. The switch is put into short circuit current limiting mode if the switch is loaded with a heavy load. When the output voltage drops below VSCTH, short circuit detection threshold voltage, the current limit value re−conditioned and short circuit current limit value is decreased to 62.5% of the current limit value. This keeps the power dissipation of the part below a certain limit even at dead short conditions at 5.5 V input voltage. The VSCTH value is set to be 1 V. At around 1.1 V of output voltage the switch is removed from short circuit current limiting mode and the current limit is set to the current limit value. The FPF2165R is a current limited switch that protects systems and loads which can be damaged or disrupted by the application of high currents. The core of each device is a 0.12 W P−channel MOSFET and a controller capable of functioning over a wide input operating range of 1.8−5.5 V. The controller protects against system malfunctions through current limiting, under−voltage lockout and thermal shutdown. The current limit is adjustable from 0.15 A to 1.5 A through the selection of an external resistor. 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. An under−voltage on VIN or a junction temperature in excess of 140°C overrides the ON control to turn off the switch. The FPF2165R 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. The ON pin control voltage and VIN pin have independent recommended operating ranges. The ON pin voltage can be driven by a voltage level higher than the input voltage. 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 under−voltage lockout threshold causes a controlled turn−on of the switch which limits current over−shoots. Reverse Current Blocking Upon the detection of an over−current, an input under− voltage, or an over−temperature condition, the FLAGB signals the fault mode by activating LOW. With the FPF2165R, FLAGB is LOW during the faults and immediately returns HI at the end of the fault condition. FLAGB is an open−drain MOSFET which requires a pull− up resistor between VIN and FLAGB. During shutdown, the pull−down on FLAGB is disabled to reduce current draw from the supply. The FPF2165R family has a Reverse Current Blocking feature that protects input source against current flow from output to input. For a standard USB power design, this is an important feature that protects the USB host from being damaged due to reverse current flow on VBUS. The reverse−current blocking feature is active when the load switch is turned off. If ON pin is LOW and output voltage becomes greater than input voltage, no current can flow from the output to the input. FLAGB operation is independent of the reverse current blocking and does not report a fault condition if this feature is activated. Current Limiting Thermal Shutdown 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. 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. The FPF2165R has no current limit blanking period so it remains in a constant−current state until the ON pin is deactivated or the thermal shutdown turns−off the switch. The thermal shutdown protects the die from internally or externally generated excessive temperatures. During an over−temperature condition the FLAGB is activated and the switch is turned−off. The switch automatically turns−on again if temperature of the die drops below the threshold temperature. Fault Reporting www.onsemi.com 7 FPF2165R APPLICATIONS INFORMATION Figure 15. Typical Application Setting Current Limit Input Capacitor The FPF2165R has a current limit which is set with an external resistor connected between ISET and GND. This resistor is selected by using equation (1), To limit the voltage drop on the input supply caused by transient in−rush currents when the switch is turned on into a discharged load capacitor or a short−circuit; a capacitor needs to be placed between VIN and GND. A 4.7 mF 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. I LIM + 340.1 R SET *1.0278 (eq. 1) Table 1 can be used to select RSET. A typical application would be the 500 mA current that is required by a single USB port. Using Table 1 an appropriate selection for the RSET resistor would be 570 W. Output Capacitor A 0.1 mF capacitor COUT, should be placed between VOUT and GND. This capacitor prevents parasitic board inductances from forcing VOUT below GND when the switch turns−off. Table 1. CURRENT LIMIT VARIOUS RSET VALUES RSET [W] Min. Current Limit [mA] Typ.

The maximum allowed setting for the current limit is 0.77 A and this results in a power dissipation of, 478 540 600 660 411 630 700 770 361 720 800 880 322 810 900 990 290 900 1000 1100 265 990 1100 1210 243 1080 1200 1320 225 1170 1300 1430 209 1260 1400 1540 196 1350 1500 1650 P + (I LIM) 2 R DS + (0.77) 2 0.12 + 71.148 mW (eq. 2) If the part goes into current limit the maximum power dissipation occurs when the output is shorted to ground. This is more power than the package can dissipate, but the thermal shutdown of the part activates to protect the part from damage due to excessive heating. A short on the output causes the part to operate in a constant−current state dissipating a worst case power of, P(max) + V IN(max) I LIM(max) + 5.5 0.77 + 4.235 W (eq. 3) This large amount of power activates the thermal shutdown and the part cycles in and out of thermal shutdown so long as the ON pin is active and the short is present. www.onsemi.com 8 FPF2165R Board Layout The middle pad (pin 7) should be connected to the GND plate of PCB for improving thermal performance of the load switch. An improper layout could result higher junction temperature and triggering the thermal shutdown protection feature. This concern applies when the switch is set at higher current limit value and an over−current condition occurs. In this case power dissipation of the switch (PD = (VIN − VOUT) x ILIM(max)) could exceed the maximum absolute power dissipation of 1.2 W. 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 helps minimize parasitic electrical effects along with minimizing the case−to−ambient thermal impedance. www.onsemi.com 9 MECHANICAL CASE OUTLINE PACKAGE DIMENSIONS WDFN6 2x2, 0.65P CASE 511CY ISSUE O 0.05 C 2.0 DATE 31 JUL 2016 A 1.72 2X 1.68 B 6 4 0.15 2.0 1.21 0.90 2.25 0.52(6X) 0.05 PIN#1 IDENT TOP VIEW C 1 2X 3 0.42(6X) 0.65 RECOMMENDED LAND PATTERN 0.75±0.05 0.10 C 0.20±0.05 0.08 NOTES: C SIDE VIEW 0.025±0.025 C A.
