1. Minimum VIN operation after start-up is only limited by the battery’s ability to provide the necessary power as it enters a deeply dis-

charged state.

2. Specification is guaranteed by design and not 100% production tested.

3. IQPWS is measured at VOUT. Multiply this value by VOUT/VIN to get the equivalent input (battery) current.

4. Specification is guaranteed by design and not 100% production tested.

Note: All limits are guaranteed. The parameters with min and max values are guaranteed with production tests or SQC (Statistical Quality

Control) methods.
