Application Information
1. REFERENCE INPUT & STAND-BY FUNCTION
• Reference input (PIN 27)
The applied voltage at the reference input pin must be between 1.4V and 6.5V, when V =8.5V.
CC
• Stand-by input (PIN 28)
The following input conditions must be satisfied for the normal stand-by function.
Stand-by input voltage
Stand-by input voltage
Below 0.5V or OPEN
Above 2.0V
Stand-by function is activated so the bias block and the
power block are disabled
Normal operation
2. PROTECTION FUNCTION
Thermal shutdown (TSD)
If the chip temperature rises above 175°C, the thermal shutdown (TSD) circuit is activated and the output circuit is in the mute
state, that is off state. The TSD circuit has a temperature hysteresis of 25°C
3. SEPARATION OF POWER SUPPLY
• PVcc1 (PIN 9)
PVcc1 is the power for loading driver. The range is between 5V ~ 12V.
• PVcc2 (PIN 21)
PVcc2 is the power supply for actuator driver that include focus and tracking actuator. The range is between 5V ~ 12V
• Vcc (PIN 8)
V
cc pin supplies power for sled driver and signal logic part. The voltage applied to Vcc must be higher than PVcc1 and PVcc2
at least 1V
