General Description
The FPF2116 is a load switch which provides full protection to systems and loads which may encounter large current conditions. This device contains a 0.125 current-limited P-channel MOSFET which can operate over an input voltage range of 1.8-5.5V. 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 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. When the switch current reaches the current limit, the part operates in a constant-current mode to prohibit excessive currents from causing damage. If the constant current condition still persists after 30ms, the part will shut off the switch and pull the fault signal pin (FLAGB) low. An auto-restart feature will turn the switch on again after 480ms if the ON pin is stil
l active. The minimum current limit is 200mA. The part is available in a space-saving 5 pin SOT23 package.
