4ch PWM Driver IC AN41050A
nOverview
AN41050A is a 4-channel driver IC designed for optical disks system such as CD and MD player. It has 3 PWM
( pulse width modulation) input channel and 1 linear input channel .With the implementation of PWM system,Low
power consumption and small package are achieved.
nFeature
<CH1～CH3>
lPWM input, PWM output (PVCC1=6 V min 7 V typ 9 V max)
lLow power consumption achieved by using DMOS output transistor.
lBuilt-in booster circuit for DMOS drive.
<CH4>
llinear input, PWM output (PVCC2= 6 V min 7 Vtyp 13 V max)
lLow power consumption achieved by using DMOS output transistor.
lBuilt-in booster circuit for DMOS drive of only ch4.
lControllable carrier frequency by external capacitor adjustment (pin CT).
(Frequency is 100 kHz when external capacitor is 100 pF.)
lControllable driver input/output gain by external resistance adjustment.
<OTHERS>
lIncorporating one general-purpose OP-Amp.
lIncorporating thermal shutdown circuit.
lIncorporating stand-by function that mutes all the channels.
lIncorporating SVCC/VREF reset function.
lExcellent heat radiation characteristics is available by mounting heat sink of bottom side.
nApplications
Audio CD, MD and DVD-player actuator and motor driver applications
