Full Function Load Switch With Reverse Current Blocking

The FPF2180 FPF2182 FPF2183 FPF2184 FPF2186 FPF2187 is a series of load switches which provides full protection to systems and loads which may encounter large current conditions. These devices contain a 55m& 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. 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.
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 FPF2180 82/84/86, if the constant current condition still persists after 30ms, the part will shut off the Switch and pull the fault signal pin (FLAGB) low. The FPF2180 84 have an auto-restart feature which will turn the Switch on again after 450ms if the ON pin is still active. The FPF2182 86 do not have this auto-restart feature so the Switch will remain off until the ON pin is cycled. For the FPF2183 87, 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. The minimum current limit is 200mA for the FPF2180 82/83 while that for the FPF2184 86/87 is 400mA.
These parts are available in a space-saving 6 ball advanced. Pb-Free 1 x 1.5 mm CSP package.
