FPF2500-FPF2506 IntelliMAX™ Advanced Load Management Products February 2007 FPF2500-FPF2506 IntelliMAX™ Advanced Load Management Products Features „ 4.5 to 20V Input Voltage Range „ Controlled Turn-On „ 0.4A, 0.8A and Adjustable Current Limit Option „ Undervoltage Lockout „ Thermal Shutdown „ <10uA Shutdown Current „ Auto Restart „ Fault Blanking tm General Description The FPF2500 through FPF2506 is a family of load switches which provide full protection to systems and loads which may encounter large current conditions. These devices contain a 0.23Ω current-limited N-channel MOSFET which can operate over an input voltage range of 4.5-20V. 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 FPF2500, FPF2501, FPF2503 and FPF2505, if the constant current condition still persists after 5ms, these parts will shut off the switch and, for the FPF2503 and FPF2505, the fault signal pin (FLAGB) will be pulled low. The FPF2500, FPF2503, and FPF2505, have an auto-restart feature which will turn the switch on again after 640ms if the ON pin is still active. The FPF2501 does not have this auto-restart feature so...
