... Notes When Using The TA7267BP The full bridge driver, TA7267BP specifically developed to control rotation switching in brush motors. This IC has been carefully designed and strengthened to withstand counter−electromotive force or start up rush current, which are problems in driving brush motors. However, as with other power ICs, application circuits must be designed not to apply surge voltage or excess current that exceeds the standard values ...

... Otherwise, the current or power consumption may exceed the absolute maximum rating, and exceeding the rating(s) may cause the device breakdown, damage or deterioration, and may result injury by explosion or combustion. In addition, do not use any device that is applied the current with inserting in the wrong orientation or incorrectly even just one time. 11 TA7267BP 2007-2-28 ...
