... Motor drive modes can be selected depending on the type of motors to be driven. The configuration of H-bridge drivers and control category are changed according to the selected mode. There is basically no need to change drive modes during motor operation. Thus, the TB62212FTAG does not support dynamic mode switching. ...

... The digital tBLANK time becomes effective only in DC Motor mode. The TB62212FTAG enters 37.5% Mixed-Decay mode when starting DC motor operation. In this mode, the TB62212FTAG stays in Charge mode for the first 3 CLK cycles of the whole period, which is also a digital tBLANK time. Thus, depending on the timing, operation mode might be switched directly to Fast-Decay mode. ...

... DC voltage will increase. If this output voltage is connected to a speaker with low input withstand voltage, over-current or IC failure can cause smoke or ignition. (The over-current can cause smoke or ignition from the IC itself.)
