Note: The absolute maximum ratings of a semiconductor device are a set of ratings that must not be exceeded, even
Note 1: OUT1, OUT2
Note 2: The absolute maximum output current rating of 4.5 A must be kept for OUT1 and OUT2 when VM  36 V.
Note 3: The absolute maximum output current rating of 4.0 A must be kept for OUT1 and OUT2 when VM 36 V.

*: The average output current shall be increased or decreased depending on usage conditions such as ambient
temperature and IC mounting method).
Use the average output current so that the junction temperature of 150°C (T
current rating of 4.5 A or 4.0 A are not exceeded.
for a moment. Do not exceed any of these ratings.
Exceeding the rating (s) may cause the device breakdown, damage or deterioration, and may result injury by
explosion or combustion.
Please use the TB6642FG within the specified operating ranges.
