Note 1.

Note 4.
Note 5.
Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
Measured at RC. Signal amplitude tracks V DD .
The COMP pin is internally clamped to 3.65V(typ). The COMP pin source current is tested at V COMP = 3.0V to avoid interfering with this clamp
voltage. The minimum source current increases as V COMP approaches V CLAMP .
Note 6.
Gain is defined by A =
? V COMP
? V CS
, 0 ≤ V CS ≤ 0.4V.
Note 7.
Note 8.
Note 9.
Parameter measured at trip point of latch with FB at 0V.
The internal current sink on the CS pin is designed to discharge an external filter capacitor. It is not intended to be a DC sink path.
For MIC3808, set V DD above the start threshold before setting at 10V.
Note 10. Does not include current in the external oscillator network.
Note 11. Maximum operating voltage is equal to the V DD [zener] shunt voltage. When operating at or near the shunt voltage, care must be taken to limit
the V DD pin current to less than the 20mA V DD maximum supply current rating.
Note 12. Start threshold and Zener Shunt threshold track one another.
