Voltage [ 1.25V ]
R2
R3
IHys
R1
R4
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.
[Except Tray, Input 2 OPAMP. those are only controlled by SVcc. ]

BTL Driver Circuits are composed of VI-Converter, Level Shifter and Output power AMP.
VI-Converter converts voltage of Vin into current [Iconv ]
Iconv = (Vin – Bias ) / R1[10KΩ]
►Closed Loop Voltage Gain
Gain = 20 log [2× (15K/10K)×{1+(20K/10K)} ]
= 19.08 [dB]
►Gain Control by Using external resistor
Gain = 20 log [2× (15K/Rext+10K)×{1+(20K/10K)} ]

Input circuit of pin1 [FWD] and pin2 [REV] is designed to avoid simultaneous activation of upper and
lower output power TR. however, in order to improve reliability, apply motor forward/reverse
input once through open mode. We recommend that the time period of open state is longer than 10msec.
“H” side output voltage on output voltage [VOL+, VOL-] varies depending on output control terminal
for tray. [pin3]“H” side output voltage is set three times (9.2dB typ.) LDCONT [pin3], and “L” side
output voltage is equal to output saturation voltage.
