FPF2193 Protected Power Switches by ON Semiconductor

Full Function Load Switch with Adjustable Current Limit


The FPF2193 load switch provides full protection to systems and loads that may encounter large current conditions. These devices contain a 55mΩ current-limited Pchannel MOSFET that can operate over an input voltage range of 1.8 to 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 that 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. If the constant current condition still persists after 30ms, the parts shut off the switch and pull the fault signal pin (FLAGB) LOW. The FPF2193 has an auto-restart feature that turns the switch on again after 450ms if the ON pin is still active. The minimum current limit is 100mA. These parts are available in a space-saving six ball advanced 1 x 1.5mm WLCSP package.
