TA2058F

The TA2058F is a power driver IC developed for CD players.This IC have built-in 4 channel BTL power amplifiers which drives focus-coil and tracking coil for 3-beam pick-up head,disc motor and feed motor.

Features of the TA2058F are:(1)4 channel BTL linear divers;(2)few external parts;(3)fixed voltage gain is Gv=15 dB(Typ.);(4)high output power : VOM1=5Vp-p (Typ.) Vcc=5V,RL=50HM,VOM2=6Vp-p (Typ.) Vcc=6V,RL=50HM;(5)thermal shut down protector;(6)input reference voltage short protector;(7)small package is power-flat package 1mm pitch 20pins;(8)operation supply voltage range is Vcc(opr)=4.0 to 10.0V (Ta=25).

The absolute maximum ratings of the TA2058F can be summarized as:(1):the parameter is supply voltage,the symbol is VCC,the rating is 14,the unit is V;(2):the parameter is power dissipation,the symbol is PD,the rating is 2,the unit is W;(3):the parameter is operating temperature,the symbol is Topr,the rating is -30 to 85,the unit is ;(4):the parameter is storage temperature,the symbol is Tstg,the rating is -55 to 150,the unit is .The mounted on 50mm * 50mm * 1.6mm size board with copper area 60% over.The derated above Ta=25,in the proportion of 62.5mW/.
