Application Information
1. Thermal Shut Down Circuit
Focus, Tracking, Tray, Spindle,
Sled, Con. Current
Reg. Bandgap
Voltage [ 1.25V ]
R2
R3
R4
R1
IHys
The built-in thermal shutdown circuit mutes the output current when the chip temperature
reaches 175℃(typ.). The hysteresis is set to 25℃(typ.) by IHys,
so the circuit will start up again when the chip temperature falling to 150℃(typ.)
VCC
2. Comparator Circuit
Pull up Resistor
