(2) connecting the power supply connector backward connecting of the power supply in reverse polarity can damage the ic. take precautions when connecting the power supply lines. an external direction diode can be added. (3) power supply lines design the pcb layout pattern to provide low impedance gnd and supply lines. to obtain a low noise ground and supply line, separate the ground section and supply lines of the digital and analog blocks . furthermore, for all power supply terminals to ics , connect a capacitor between the power supply and gnd te rminal. when using electrolytic capacitors in a circuit, not e that capacitance values are reduced at low temperatures and over time. (4) gnd voltage the potential of the gnd pin must be minimum potential under all operating conditions. (5) thermal design use a thermal design that allows for a sufficient margin in light of the power dissipation (pd) in actual operating condition s. (6) off - leakage at high temperature. off - leak age at high temperature may increase because of manufacturing variations. design should consider the typ ical & worst cases shown below. (7) inter - pin shorts and mounting errors use caution when positioning the ic for mounting on printed circuit boards. the ic may be damaged if t here is any connection error or if pins are shorted together. (8) actions in strong electromagnetic field use caution when using the ic in the presence of a strong electromagnetic field as doing so may caus e the ic to malfunction. (9) aso when using the ic, set the output transistor so that it does not exceed absolute maximum ratings or aso. (10) thermal shutdown circuit the ic incorporates a built - in thermal shutdown circuit (tsd circuit). the thermal shutdown circuit (tsd c ircuit) is designed only to shut the ic off to prevent thermal runaway. 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 o peration of this circui t is assumed. ts d on temperature[ ] (typ.) hysteresis temperature [ ] (typ.) bd xxia5 wefj 175 15 ta-ileak 0 0.1 0.2 0.3 0.4 0.5 25 50 75 100 125 150 temperature () ileak (ma) typ worst downloaded from: http:///

(12) regarding input pin of the ic this monolithic ic contains p+ isolation and p substrate layers between adjacent elements in order to keep them isolated. p- n junctions are formed at the intersection of these p layers with the n layers of other elements , creating a parasitic diode or transistor. for example, the relation between each potential is as follows: when gnd > pin a and gnd > pin b, the p - n junction operates as a parasitic diode. when gnd > pin b, the p - n junction operates as a parasitic transistor. parasitic diodes can occur inevitable in the structure of the ic. the operation of parasitic diodes can result in mutual interference among circuits, operational faults, or physical damage. accordingly, method s by which parasitic diodes operate, such as applying a voltage that is lower than the gnd (p substrate) voltage to an input pin, should not be used. (13) ground wiring pattern. when using both small signal and large current gnd patterns, it is rec ommended to isolate the two ground patterns, placing a single ground point at the ground 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 v oltage. be careful not to change the gnd wiring pattern of any external components, either. resistor transistor (npn) n n n p + p + p p substrate gnd parasitic element pin a n n p + p + p p substrate gnd parasitic element pin b c b e n gnd pin a parasitic element pin b other adjacent elements e b c gnd parasitic element downloaded from: http:///
