While the FO pin is in the low state, all the low-sidetransistors turn off. In normal operation, the FO pinoutputs a high signal of about 5 V. Motor operations mustbe controlled by the external microcontroller so that it canimmediately stop the motor when fault signals aredetected. To prevent the IC from having permanentdamage at OCP activation, be sure to set the motoroperation to stop within tP = 25 μs (typ.). tP is the faultsignal output time of the FO pin, fixed by a built-infeature of the IC itself (see Section 12.3.5). To resume themotor operation thereafter, set the motor to be resumedafter a lapse of ≥2 seconds.
