Notes:
1. Exceeding the absolute maximum rating may damage the device.
2. The device is not guaranteed to function outside its operating rating.
3. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
4. Specification for packaged product only.
5. OFF is V_EN < 1.0V for MIC2040/MIC2041–1 and V_EN > 4.0V for MIC2040/MIC2041 –2. ON is V_EN > 4.0V for MIC2040/MIC2041–1 and
V_EN < 1.0V for MIC2040/MIC2041 –2.
6. The current limit is determined as follows: I_LIM = CLF/R_SET.
