AN41252A 1 7 sdc00076aeb 1) please carry out the thermal design with sufficient margin such that the power dissipation will not be exceeded, based on the conditions of power supply, load and ambient temperature. 2) protection circuit has been built-in to ensure the safety in the event of abnormal operation. therefore, please design such that the protection circuit does not work during normal operation. especially in the over-temperature protection circuit, if the ar ea of safe operation or the absolute maximum rating is momentarily exceeded, as in the event of output pin to v dd short (power supply fault), or output pin to gnd short (ground fault), then the lsi might be damaged before the over-temperature protection circuit could operate. 3) pay attention in the pattern layout in order to prevent damage due to short circuit between pins. in addition, for the pin configuration, please refer to the ? pin descriptions. 4) unless specified in the product specifications, please make sure that negative voltage or excessive voltage are not applied to the pins because the device might be damaged, which could happen due to negative voltage or excessive voltage generated during the on and off timing when the inductive load of a motor coil or actuator coils of optical pick-up is being driven. 5) be sure not to mount the lsi in the reverse direction onto the pcb. it might be damaged when the electricity is turned on. 6) perform a visual inspection on the printed-circuit-board before turning on the power supply, otherwise damage might happen due to problems such as a solder-bridge between the pins of the semiconductor device. also, perform a full technical verification on the assembly quality, because the same damage possibly can happen due to conductive substances, such as solder ball, that adhere to the lsi during transportation. 7) take notice in the use of this product that it might break or occasionally smoke when an abnormal state occurs such as output pin-v dd short, output pin-gnd short, or output-to-output-pin short (load short). and, safety measures such as an installation of fuses are recommended because the extent of the above-mentioned damage and smoke emission will depend on the current capability of the power supply. 8) when using the lsi for model development or new products, perform fully the safety verification including the long-term reliability for each product. 9) verify the risk due to the breakdown of external parts. 13. notes of power lsi ? usage notes (continued) maintenance/ discontinued maintenance/discontinued includes following four product lifecycle stage. planed maintenance type maintenance type planed discontinued typed discontinued type please visit following url about latest information. http://www.semicon.panasonic.co.jp/en/
