(2). connecting the power supply connector backward connecting of the power supply in reverse polarity can damage ic. take precautions when connecting the power supply lines. an external direction diode can be added. (3). power supply lines design 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 s upply lines of the digital and analog blocks. furthermore, for all power supply terminals to ics, connect a capacitor between the power supply and the gnd terminal. when applying electrolytic capacitors in the circuit, not that capacitance char acteristic values are reduced at low temperatures. (4). gnd voltage the potential of gnd pin must be minimum potential in 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 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 presence of a strong electromagnetic field 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 ratings or aso. (9). thermal shutdown circuit the ic incorporates a built-in thermal shutdown circuit (tsd circuit). the thermal shutdown circuit (tsd circuit) is designed only to shut the ic off to prevent thermal runaw ay. 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. (10). testing on application boards when testing the ic on an application board, 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 precaution when transporting or storing the ic. tsd on temperature[ ] (typ.) hysteresis temperature [ ] (typ.) bdxxga3mefj-lb 175 15

(12). ground 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 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 voltage. 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 pin a n n p + p + p p substrate gnd parasitic element pin b c b e n gnd pin a pin b other adjacent elements e b c gnd p aras iti c element p aras iti c element parasitic element
