(Warning) The protector functions only improve the IC’s tolerance and they do not guarantee the safety of the IC if used under the
conditions out of safety range or ratings. Use of the IC such as use under overcurrent protection range, thermal shutdown
state or V6IN OVS condition may degrade the IC’s reliability and eventually damage the IC.

(*1) All the specification is defined based on the tests performed under the conditions where Tj and Ta(=25°C) are almost equal. These tests were performed
with pulse load to minimize the increase of junction temperature (Tj).
