... If the power supply is not equipped with sink capability, the power and output pins may exceed the maximum rating. The counter-electromotive force of the motor will vary depending on the conditions of use and the features of the motor. Therefore make sure there will be no damage to or operational problem in the IC, and no damage to or operational errors in peripheral circuits caused by counter-electromotive force. 21 TB6556F/FG 2005-01-19 ...
