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.
All voltages are referenced to ground.
For MIC2070-1(P) OFF occurs when VEN < 0.8V and ON occurs when VEN > 2.4V. For MIC2070-2(P) OFF occurs when VEN > 2.4V and ON
occurs when VEN < 0.8V.
Current-limit threshold is defined by the current-limit factor divided by RSET.
Guaranteed by design. Not production tested.
Assumes only one channel in current-limit. Delay circuitry is shared among channels so it is possible for tDLY to be 40ms max if one channel
enters current-limit as the other is about to time-out.
Cross conduction time is the duration in which both MAIN and AUX internal switches are on subsequent to S3# transitioning.
