FPF2105 ON Semiconductor

DATA SHEET www.onsemi.com IntelliMAX Advanced Load Management Products FPF2100 - FPF2107 SOT235 CASE 527AH Description The FPF2100 through FPF2107 is a family of load switches which provide full protection to systems and loads which may encounter MARKING DIAGRAM large current conditions. These devices contain a 0.125 currentlimited Pchannel MOSFET which can operate over an input voltage range of 1.8 5.5 V. Switch control is by a logic input (ON) &E&E&Y capable of interfacing directly with low voltage control signals. Each &O210X&C part contains thermal shutdown protection which shuts off the switch &.&O&E&V to prevent damage to the part when a continuous overcurrent condition causes excessive heating. When the switch current reaches the current limit, the part operates &E = Designates Space in a constantcurrent mode to prohibit excessive currents from &Y = Binary Calendar Year Coding Scheme causing damage. For the FPF2100FPF2102 and FPF2104FPF2106, &O = Plant Code identifier if the constant current condition still persists after 10 ms, these parts 210X = Device Specific Code will shut off the switch and pull the fault signal pin (FLAGB) low. X = 0, 1, 2, 3, 4, 5, 6, 7 The FPF2100, FPF2101, FPF2104 and FPF2105, have an autorestart &C = Single digit Die Run Code &. = Pin One Dot feature which will turn the switch on again after 160 ms if the ON pin &V = EightWeek Binary Datecoding Scheme is still active. The FPF2102 and FPF2106 do not have this autorestart feature so the switch will remain off until the ON pin is cycled. FortheFPF2103 and FPF2107, a current limit condition will ORDERING INFORMATION immediately pull the fault signal pin low and the part will remain in See detailed ordering and shipping information on page 11 the constant current mode until the switch current falls below of this data sheet. the current limit. For the FPF2100 through FPF2103, the minimum current limit is 200 mA while that for the FPF2104 through FPF2107 is 400 mA. These parts are available in a spacesaving 5 pin SOT23 package.
