Application Information
- Thermal Shut Down Circuit 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.) 2. Regulator Circuit -. The Ref. V oltage is generated by the internal circuit [Band gap reference] -. It needs to attach an external power TR [* AUK PNP Power TR : STA353 *] -. The output voltage of the regulator is calculated depend on R1 and R2’s values. 2.5V [R1: 10K / R2 : 10K] Reg. Bandgap V oltage [ 1.25V ] Focus, Tracking, Tray, Spindle, Sled , Con.

SEPT., 2010 REV . 03 3. Bias & Mute Circuit Bias pin (pin 27) should be pulled up to more than 1.2V . In case the bias pin’s voltage is pulled down below 1.2V (typ.), the output current is muted, also Mute pin is same as Bias pin. [Except Tray, Regulator, Comparator, those are only controlled by Vcc1. ] 4. Comparator Circuit The Comparator is construction of open collector with external pulled up Resister for observation status of spindle motor. Focus, Tracking, Sled Spindle Con.
