4/4 rev. b ? i/o switching waveform ? operation notes (1) absolute maximum ratings use of the ic in excess of absolute maximum ratings such as the applied voltage or operating temperature range (topr) may result in ic damage. assumptions should not be made regarding the state of the ic (short mode or open mode) when such damage is suffered. the implementation of a physical safety meas ure such as a fuse should be considered when use of the ic in a special mode where the absolute ma ximum ratings may be exceeded is anticipated. (2) power supply lines regenerated current may flow as a result of the motor's back electromotive force. insert capacitors between the power supply and ground pins to serve as a route for regenerated current . determine the capacitance in full consideration of all the characteristics of the electrolytic capacitor, because the electrolytic capaci tor may loose some capacitance at low temperatures. if the connected power supply does not have suffic ient current absorption capacity, regenerative current will cause the voltage on the power supply line to rise, which combined with the product and its peripheral circuitry may exceed the absolute maximum ratings. it is recommended to implement a physical safety measure such as the insertion of a voltage clamp diode between the power supply and ground pins. (3) ground potential ensure a minimum gnd pin potenti al in all operating conditions. (4) setting of heat use a thermal design that allows for a sufficient margin in li ght of the power dissipation (pd) in actual operating conditions. (5) actions in strong magnetic field use caution when using the ic in the presence of a strong magnetic field as doi ng so may cause the ic to malfunction. (6) aso when using the ic, set the output transistor for the motor so that it does not exceed absolute maximum ratings or aso. (7) thermal shutdown circuit this ic incorporates a tsd (thermal shut down) circuit (tsd circuit). if the temper ature of the chip reaches the following temperature, the motor coil output will be opened. the thermal shut down circuit (tsd circuit) is designed only to shut the ic off to prevent runaway thermal operation. it is not designed to protect the ic or guarantee its operation. do not continue to use the ic after operating this circuit or use the ic in an environment where the operation of this circuit is assumed. tsd on temperature [c] (typ.) hysteresis temperature [c] (typ.) 175 25 (8) ground wiring pattern when using both small signal gnd and large current gnd pattern s, it is recommended to isolate the two ground patterns, placing a single ground point at the applicat ion's reference point so that the pattern wiring resistance and voltage variations caused by large currents do not cause variations in the small signal ground voltage. be careful not to change the gnd wiring pattern of any external components, either. fi g .5 bd6360gul i/o switchin g waveform 100% 0% 100% 0% -100% ton ton toff toff tf tr tf tr 50% 50% 50% 50% -50% -50% 90% 10% -10% -90% -90% -10% 10% 90% motor current vin
