No destruction mode (e.g., short-circuiting or open) can be specified in that case. If such special mode as will exceed absolute maximum ratings is assumed, take the physical safety measures, such as a fuse. (2) Power supply lines The regenerated current by BEMF of the motor will return. Therefore, take measures, such as the insertion of a capacitor between the power supply and GND as the pass of the 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 connected power supply does not have sufficient current absorption capacity, regenerative current will cause the voltage of the power supply line to rise, which the product and its peripheral circuit may exceed the absolute maximum ratings. It is recommended to implement physical safety measures such as the insertion 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) Design for heat Use the design for heat that allows for a sufficient margin in light of the power dissipation (Pd) in actual using conditions. (5) Operation in strong magnetic field Use caution when using the IC in the strong magnetic field as doing so may cause the IC to malfunction. (6) ASO When using the IC, make settings so that the output transistors for the motor will not be used under conditions in excess of the absolute maximum ratings and ASO. (7) Thermal shutdown circuit This IC incorporates thermal shutdown circuit(TSD circuit). When the chip temperature becomes the one shown in below, TSD circuit operates and makes the coil output to motor open. It is designed to shut the IC off from 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[℃] (typ.) Hysteresis temperature 175 (8) [℃] (typ.) 25 Ground wiring pattern When having both small signal and large current GND, it is recommended to isolate the two GND 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 cause voltage variations of the small signal GND. Be careful not to change the GND wiring pattern of any external parts, either. REV.
