FPF2106

FAIRCHILD SEMICONDUCTOR  FPF2106  电源负载开关, IntelliMAX, 高压侧, 高电平有效, 1路输出, 5.5V, 0.6A, SOT-23-5

The is a Full Function Load Switch which provides full protection to systems and loads which may encounter large current conditions. This device contains a 0.125W current-limited P-channel MOSFET which can operate over an input voltage range of 1.8 to 5.5V. 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. The FPF2106 do not have this auto-restart feature so the switch will remain off until the ON pin is cycled.
