MIC2025/2075 Micrel, Inc. MIC2025/2075 Single-Channel Power Distribution Switch MM8 General Description Features The MIC2025 and MIC2075 are high-side MOSFET switches 140m maximum on-resistance optimized for general-purpose power distribution requiring 2.7V to 5.5V operating range circuit protection. 500mA minimum continuous output current Short-circuit protection with thermal shutdown The MIC2025/75 are internally current limited and have Fault status flag with 3ms filter eliminates false asser - thermal shutdown that protects the device and load. The tions MIC2075 offers smart thermal shutdown that reduces cur- Undervoltage lockout rent consumption in fault modes. When a thermal shutdown Reverse current flow blocking (no body diode) fault occurs, the output is latched off until the faulty load is Circuit breaker mode (MIC2075) reduces power removed. Removing the load or toggling the enable input will consumption reset the device output. Logic-compatible input Both devices employ soft-start circuitry that minimizes inrush Soft-start circuit current in applications where highly capacitive loads are em- Low quiescent current ployed. A fault status output flag is provided that is asserted Pin-compatible with MIC2525 during overcurrent and thermal shutdown conditions. UL File E179633 The MIC2025/75 is available in the MM8 8-lead MSOP and 8-lead SOP.
