3/3 rev. d cautions on use 1) absolute ma ximum ratings an excess in the absolute maximum rations, such as supply voltage, temperature range of operating conditions, etc., can break down the devices, thus making impossible to i dentify breaking mode, such as a short circuit or an open circuit. if any over rated values will expect to exceed the absolute maximum ratings, consider adding circuit protection devices, such as fuses. 2) connecting the power supply connector backward connecting of the power supply in reverse polarity ca n damage ic. take precautions when connecting the power supply lines. an external direction diode can be added. 3) power supply line back electromotive force causes regenerated current to power supply line, therefore take a measure such as placing a capacitor between power supply and gnd for routing regenerated current. and fully ensure that the capacitor characteristics have no problem before determine a capacitor value. (when applying electrolytic capacitors, capacitance characteristic values are reduced at low temperatures) 4) gnd potential it is possible that the motor output terminal may de flect below gnd terminal because of influence by back electromotive force of motor. the potential of gnd terminal must be minimum potential in all operating conditions, except that the levels of the motor outputs terminals are under gnd level by the back electromotive force of the motor coil. also ensure that all terminals except gnd and moto r output terminals do not fall below gnd voltage including transient characteristics. malfunction may possibly occur depending on use condition, environment, and property of individual motor. please make fully confirmati on that no problem is found on operation of ic. 5) thermal design use a thermal design that allows for a sufficient margin in light of the po wer dissipation(pd) in actual operating conditions. 6) inter-pin shorts and mounting errors use caution when positioning the ic for mounting on printed circuit boards. the ic may be damaged if there is any connection error or if pins are shorted together. 7) actions in strong electromagnetic field use caution when using the ic in the pr esence of a strong electromagnetic fi eld as doing so may cause the ic to malfunction. 8) aso when using the ic, set the output transistor so that it does not exceed absolute maximum rations or aso. 9) thermal shut down circuit the ic incorporates a built-in thermal shutdown ci rcuit (tsd circuit). operation temperature is 175 (typ.) and has a hysteresis width of 25 (typ.). when ic chip temperature rises and ts d circuit works, the output terminal becomes an open state. tsd circuit is designed only to shut the ic of f to prevent thermal runaway. it is not designed to protect the ic or guarantee its operation. do not continue to use the ic after operation this circuit or use the ic in an environment where the operation of this circuit is assumed. 10) testing on application boards when testing the ic on an application boar d, connecting a capacitor to a pin with low impedance subjects the ic to stress. always discharge capacitors after each process or step. always turn the ic?s power supply off before connecting it to or removing it from a jig or fixture during the inspection process. ground the ic during assembly steps as an antistatic measure. use similar prec aution when transporting or storing the ic. 11) gnd wiring pattern when using both small signal and large current gnd patterns, it is recommended to isolate the two ground patterns, placing a single ground point at the gr ound potential of application 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. 12) capacitor between output and gnd when a large capacitor is connected between output and gnd, if vcc is shorted with 0v or gnd for some cause, it is possible that the current charged in the capacitor may flow into the output resulting in destruction. keep the capacitor between output and gnd below 100uf. 13) ic terminal input when vcc voltage is not applied to ic, do not apply voltage to each input terminal. when voltage above vcc or below gnd is applied to the input terminal, parasitic element is ac tuated due to the structure of ic. operation of parasitic element causes mutual interference between circuits, resulti ng in m alfunction as well as destruction in the last. do not use in a manner where parasitic element is actuated.
