... Both devices employ soft-start circuitry that minimizes inrush current in applications where highly capacitive loads are employed. A fault status output flag is provided that is asserted during overcurrent and thermal shutdown condi- tions. The MIC2025/75 is available in the MM8™ 8-lead MSOP and 8-lead SOP. Typical Application Logic Controller VIN OVERCURRENT 1µ ...

... C. The MIC2025 will automatically reset its output should the die temperature cool down to 120 C. The MIC2025 output and FLG signal will continue to cycle on and off until the device is disabled or the fault is removed. Figure 2 depicts typical timing. If the MIC2075 goes into thermal shutdown, its output will latch off and a pull-up current source is activated ...

... See the Short-Circuit Transient Response graph under Functional Characteristics. Current-Limit Response—Ramped Load The MIC2025/75 current-limit profile exhibits a small foldback effect of about 200mA. Once this current-limit threshold is exceeded the device switches into a constant current mode important to note that the device will supply current until the current-limit threshold is exceeded ...

... Printed Circuit Board Hot-Plug The MIC2025/75 are ideal inrush current-limiters suitable for hot-plug applications. Due to the integrated charge pump, the MIC2025/75 presents a high impedance when off and slowly becomes a low impedance as it turns on. This “soft- start” feature effectively isolates power supplies from highly capacitive loads by reducing inrush current during hot-plug events ...
