Under development 4ch PWM Driver IC AN41050A n Overview 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. n Feature l PWM input, PWM output (PVCC1=6 V min 7 V typ 9 V max) l Low power consumption achieved by using DMOS output transistor. l Built-in booster circuit for DMOS drive. l linear input, PWM output (PVCC2= 6 V min 7 Vtyp 13 V max) l Low power consumption achieved by using DMOS output transistor. l Built-in booster circuit for DMOS drive of only ch4. l Controllable carrier frequency by external capacitor adjustment (pin CT). (Frequency is 100 kHz when external capacitor is 100 pF.) l Controllable driver input/output gain by external resistance adjustment. l Incorporating one general-purpose OP-Amp. l Incorporating thermal shutdown circuit. l Incorporating stand-by function that mutes all the channels. l Incorporating SVCC/VREF reset function. l Excellent heat radiation characteristics is available by mounting heat sink of bottom side. n Applications Audio CD, MD and DVD-player actuator and motor driver applications n Package Unitmm 1.20(max.) 6.100.10 8.100.20 14.000.10 0.50 The products and specification are subject to change without any notice.
