7 / 8 page 734 Optical disc ICs BA5916FP-Y FOperation notes (1) The BA5916FP-Y contains a thermal shutdown cir- cuit. When the chip temperature reaches 175 _C (Typ.), the output current is muted. If the chip temperature then drops below 150 _C (Typ.), then the mute is released. (2) By having the standby pin (pin 8) voltage open or lowered to 0.5V or below, the drivers turn off and the IC enters the power saving mode. For normal operation, have the standby pin (pin 8) volt- age pulled up to 2.0V or greater. (3) If the voltage of the bias pin (pin 2) drops below 1.0V (Typ.), outputs are muted. For normal conditions, have the voltage above 1.4V. (4) If the voltage of the thermal shutdown or bias pin drops, the mute is activated; however, in these situations, only the drivers are muted. Also, the output pin voltage becomes the internal bias voltage (approx. VCC *VF/2). (5) Connect a bypass capacitor (approx. 0.1 µF) be- tween the bases of the power supply pins of this IC. (6) Even though the radiation fins are connected to ground within the package, be sure to also connect them to a ground externally as well. FElectrical characteristic curves |
