Example Application Circuits
The values shown in the following figure are typical values. For input conditions, see the Operating Ranges.
Note: Bypass capacitors should be added as necessary.
It is recommended to use a single ground plane for the entire board whenever possible, and a grounding
method should be considered for efficient heat dissipation.
In cases where mode setting pins are controlled via switches, either pull-down or pull-up resistors should be
added to them to avoid floating states.
For a description of the input values, see the function tables.
The above application circuit example is presented only as a guide and should be fully evaluated prior to
production. Also, no intellectual property right is ceded in any way whatsoever in regard to its use.
The external components in the above diagram are used to test the electrical characteristics of the device: it is
not guaranteed that no system malfunction or failure will occur.
Careful attention should be paid to the layout of the output, V
DD
(V
M
) and GND traces to avoid short-circuits across output pins or to
the power supply or ground. If such a short-circuit occurs, the TB62214AFNG 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 TB62214AFNG does not have an overvoltage protection circuit. Thus, if a voltage exceeding the rated maximum
voltage is applied, the TB62214AFNG will be damaged; it should be ensured that it is used within the specified operating conditions.
