Current Reg. Bandgap Voltage [ 1.25V ] R2 R3 IHys R4 R1 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] Bias & Mute Circuit Focus, Tracking, Sled Spindle Con. Current Bias Mute R1 R3 R2 R4 Bias pin (pin 28) 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.
