Example Application Circuits
Careful attention should be paid to the layout of the output, V
the power supply or ground. If such a short-circuit occurs, the TB62214FNG may be permanently damaged. Also, if the device is
installed in a wrong orientation, a high voltage might be applied to components with lower voltage ratings, causing them to be
damaged. The TB62214FNG does not have an overvoltage protection circuit. Thus, if a voltage exceeding the rated maximum voltage
is applied, the TB62214FNG will be damaged; it should be ensured that it is used within the specified operating conditions.
Note: Bypass capacitors should be added as necessary.

not guaranteed that no system malfunction or failure will occur.
The values shown in the following figure are typical values. For input conditions, see the Operating Ranges.
It is recommended to use a single ground plane for the entire board whenever possible, and a grounding
In cases where mode setting pins are controlled via switches, either pull-down or pull-up resistors should be
For a description of the input values, see the function tables.
