Full Function Load Switch with Adjustable Current Limit FPF2165R Description www.onsemi.com The FPF2165R is a load switch which provides full protection to systems and loads which may encounter large current conditions. The device contains a 0.12 currentlimited Pchannel MOSFET which can operate over an input voltage range of 1.85.5 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 lowvoltage (Bottom) (Top) Pin 1 control signals. The FPF2165R contains thermal shutdown protection, WDFN6 2x2, 065P which shuts off the switch to prevent damage to the part when a CASE 511CY continuous overcurrent condition causes excessive heating. When the switch current reaches the current limit, the part operates in a ConstantCurrent (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 spacesaving 6pin 2 mm x 2 mm Molded Leadless Package (MLP).
