MIC2025/2075 Single-Channel Power Distribution Switch Features General Description 140 m Maximum On-Resistance The MIC2025 and MIC2075 are high-side MOSFET switches optimized for general-purpose power 2.7V to 5.5V Operating Range distribution requiring circuit protection. 500 mA Minimum Continuous Output Current The MIC2025/75 are internally current limited and have Short-Circuit Protection with Thermal Shutdown thermal shutdown that protects the device and load. Fault Status Flag with 3 ms Filter Eliminates False The MIC2075 offers smart thermal shutdown that Assertions reduces current consumption in fault modes. When a Undervoltage Lockout thermal shutdown fault occurs, the output is latched off Reverse Current Flow Blocking (No Body Diode) until the faulty load is removed. Removing the load or Circuit Breaker Mode (MIC2075) Reduces Power toggling the enable input will reset the device output. Consumption Both devices employ soft-start circuitry that minimizes Logic-Compatible Input inrush current in applications where highly capacitive Soft-Start Circuit loads are employed. A fault status output flag is provided that is asserted during overcurrent and Low Quiescent Current thermal shutdown conditions. Pin Compatible with MIC2525 UL File E179633 The MIC2025/75 are available in the 8-Pin MSOP and 8-Pin SOIC packages.
