CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product

reliability and result in failures not covered by warranty.

NOTES:

8. BOOT-PHASE voltage is -0.3V to -0.7V during start-up. This is due to a small current (<1mA) that flows from the battery to the PHASE pin and to an

internal current sink on the BOOT pin through an internal diode. This does not harm the part.
