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 VEN < 1.0V for MIC2042/MIC2043-1 and VEN > 4.0V for MIC2042/MIC2043-2. ON is VEN > 4.0V for MIC2042/MIC2043-1 and VEN < 1.0V for
MIC2042/MIC2043-2.
6. The current limit is determined as follows: ILIM = CLF/RSET.
