MIC2505/6 Single 2A/Dual 1A High-Side Switches Features General Description Low MOSFET On-Resistance to 3.0V The MIC2505, MIC2505-1, MIC2505-2, and MIC2506 are single and dual integrated high-side power - 30 m Typical at 5V (MIC2505 Series) switches that consist of TTL-compatible control/enable - 35 m Typical at 3.3V (MIC2505 Series) inputs, a charge pump, and protected N-channel - 75 m Typical at 5V (Each MIC2506 Output) MOSFETs. The MIC2505/6 family can be used instead - 80 m Typical at 3.3V (Each MIC2506 Out- of separate high-side drivers and MOSFETs in many put) low-voltage applications. 3.0V to 7.5V Input The MIC2505/6 family controls voltages ranging from 110 A Typical On-State Supply Current 3.0V to 7.5V. The MIC2505-series can deliver at least 1 A Typical Off-State Supply Current 2A continuous current while the MIC2506 can deliver at least 1A continuous current from each output. A slow Output Can be Forced Higher than Input turn-on feature prevents high inrush current when (Off-State) switching capacitive loads. The internal control circuitry Current-Limit is powered from the same 3.0V to 7.5V. Within the Thermal Shutdown devices input range, outputs can be forced higher than 2.5V Undervoltage Lockout (UVLO) the input voltage when disabled. Open-Load Detection (MIC2505YN/M and Multipurpose open-drain fault flag outputs indicate MIC2506YN/M Only) overcurrent limiting, open-load detection (except Open-Drain Fault Flag MIC2505-1 and -2 versions), thermal shutdown, or 5 ms (Slow) Turn-On and Fast Turn-Off undervoltage lockout for each channel. Logic-Level Control/Enable Input Overcurrent limiting is internally fixed and requires no external components. Applications Open-load detection is active when the switch is off. USB Power Distribution When off, a normal load pulls the output pin low. If the 3.3V and 5V Power Management load is open, an optional, external, high-value resistor PC Card Inrush Limiting Switch pulls the output pin high, triggering the fault flag. Hot Plug-In Power Supplies MIC2505-1 and -2 versions are tailored to Universal Battery Charger Circuits Serial Bus (USB) applications and do not include open-load detection. Thermal shutdown turns off the output if the die temperature exceeds approximately 135C. If enabled, the switch automatically restarts when the temperature falls 10C. Undervoltage lockout (UVLO) shuts off the output if the supply drops below 2.3V typical and re-enables the output when the supply exceeds 2.5V typical. 2016 - 2021 Microchip Technology Inc. and its subsidiaries DS20005579B-page 1MIC2505/6 Package Types MIC2505/-1/-2 MIC2506 8-Pin SOIC (M) 8-Pin SOIC (M) (Top View) (Top View) MIC2505/-1/-2 MIC2506 CTL A 1 8 OUT A CTL 1 8 OUT FLG A 2 7 IN FLG 2 7 IN FLG B 3 6 GND GND 3 6 OUT CTL B 4 5 OUT B GATE 4 5 IN Typical Application Schematics Single and Dual Switch/Circuit Breakers with Open-Load Detection and Fault Output 3.0V to 7.5V 3.0V to 7.5V Pull-up Pull-up Resistors Resistor MIC2505YM MIC2506YM 100N N ON 1 8 A ON 1 8 CTL OUT CTL A OUT A OFF A OFF Optional 2 7 2 7 Optional FAULT FLG IN FAULT A FLG A IN Open Load Open Load Detect Resistor 3 6 3 6 DeteResistorsFW GND OUT FAULT B FLG B GND 0.1F (MIC2505YN or MIC2505YM 4 5 B ON 4 5 GATE IN onl CTL B OUT B B OFF 0.1F Optional Output Delay Capacitor DS20005579B-page 2 2016 - 2021 Microchip Technology Inc. and its subsidiaries Load Load A Load B N HDFK N N
