... Optical disc ICs FOperation notes (1) The BA5921FP has a thermal shutdown circuit. The output current is muted when the chip temperature rises above 175_C (typically). When the chip tempera- ture falls to 150_C (typically), the driver circuit starts up again. (2) The output current can be muted by opening the mute pin (pin 9) or lowering it below 0 ...
