| FPF2500-FPF2506 IntelliMAX Advanced Load Management Products January 2008 FPF2500-FPF2506 tm IntelliMAX Advanced Load Management Products - to 20V Input Voltage Range - Controlled Turn-On - 0.4A, 0.8A and Adjustable Current Limit Option - Undervoltage Lockout - Thermal Shutdown - <10µA Shutdown Current - Auto Restart - Fault Blanking - RoHS Compliant - PDAs - Motor Drivers - Cell Phones - Digital Cameras 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 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 the switch will remain off until the ON pin is cycled. For the FPF2502, FPF2504 and FPF2506, 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. For the FPF2500 through FPF2502, the minimum current limit is adjustable from 500mA to 2A. For the FPF2503 and FPF2504 the minimum current is internally fixed at 400mA while that for the FPF2505 and FPF2506 is internally fixed at 800mA. These parts are available in a space-saving 5 pin SOT23 package.
