Notes:
1. Unless otherwise noted, all voltages referenced to VNEG. Permanent device damage may occur if the maximum
ratings are exceeded. Functional operation should be restricted to those conditions specified in the operational
sections of this data sheet. Exposure to absolute maximum rating conditions for extended periods may adversely affect
device reliability.
2. Averaged over the switching cycle.
3. VPOS is equal to VPOS1 and VPOS2 tied together for test condition purposes.
