Full Function Load Switch With Adjustable Current Limit

The FPF2193 FPF2194 and FPF2195 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 parts operate in a constant-current mode to prohibit excessive currents from causing damage. For the FPF2193 and FPF2194 if the constant current condition still persists after 30ms, these parts will shut off the Switch and pull the fault signal pin (FLAGB) low. The FPF2193 has an auto-restart feature which will turn the Switch on again after 450ms if the ON pin is still active. The FPF2194 does not have this auto-restart feature so the Switch will remain off until the ON pin is cycled. The FPF2195 will not turn off after a current limit fault, but will rather remain in the constant current mode indefinitely. The minimum current limit is 150mA.
These parts are available in a space-saving 6 ball advanced. Pb-Free 1 x 1.5 mm CSP package.
