3.General DescriptionThe MIC2505, MIC2505-1, MIC2505-2, and MIC2506are single and dual integrated high-side powerswitches that consist of TTL-compatible control/enableinputs, a charge pump, and protected N-channelMOSFETs. The MIC2505/6 family can be used insteadof separate high-side drivers and MOSFETs in manylow-voltage applications.The MIC2505/6 family controls voltages ranging from3.0V to 7.5V. The MIC2505-series can deliver at least2A continuous current while the MIC2506 can deliver atleast 1A continuous current from each output. A slowturn-on feature prevents high inrush current whenswitching capacitive loads. The internal control circuitryis powered from the same 3.0V to 7.5V. Within thedevice’s input range, outputs can be forced higher thanthe input voltage when disabled.Multipurpose open-drain fault flag outputs indicateovercurrent limiting, open-load detection (exceptMIC2505-1 and -2 versions), thermal shutdown, orundervoltage lockout for each channel.Overcurrent limiting is internally fixed and requires noexternal components.Open-load detection is active when the switch is off.When off, a normal load pulls the output pin low. If theload is open, an optional, external, high-value resistorpulls the output pin high, triggering the fault flag.MIC2505-1 and -2 versions are tailored to UniversalSerial Bus (USB) applications and do not includeopen-load detection.Thermal shutdown turns off the output if the dietemperature exceeds approximately 135°C. If enabled,the switch automatically restarts when the temperaturefalls 10°C.Undervoltage lockout (UVLO) shuts off the output if thesupply drops below 2.3V typical and re-enables theoutput when the supply exceeds 2.5V typical
