4/4 rev. a ? output ac characteristic the voltage and current waveform show the turn on time, turn off time, rise time and fa ll time when input pulse was applied at in. ? operation notes (1) absolute maximum ratings use of the ic in excess of absolute maximum ratings su ch 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 measure such as a fuse should be considered when use of the ic in a spec ial mode where the absolute maximum 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 capacitor may loose some capacitance at low temperatures. if the connecte d power supply does not have sufficient current absorption capacity, regenerative current will cause the vo ltage 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 inse rtion of a voltage clamp diode between the power supply and gnd pins. (3) ground potential ensure a minimum gnd pin potential in all operating conditions. (4) setting of heat use a thermal design that allows for a sufficient margin in light of the power dissipat ion (pd) in actual operating conditions. (5) actions in strong magnetic field use caution when using the ic in t he presence of a strong m agnetic field as doing 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 shutdown) circuit (t sd circuit). if the temperatur e of the chip reaches the following temperature, the motor coil output will be open ed. the thermal shutdown circuit (tsd circuit) is designed only to shut the ic off to prevent runaway ther mal 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 and large current gnd patte rns, it is recommended to isolate the two ground patterns, placing a single ground point at the application' s reference point so that the pattern wiring resistance and voltage variations caused by large currents do not c ause variations in the small signal ground voltage. be careful not to change the gnd wiring pattern of any external components, either. 100% 0% 0% ton toff tr tf 50% 50% 50% 50% 10% 90% 90% 10% output current in in p ut 100%
