Power Driver IC for CD Player
TA2125AF is power driver IC developed for CD players. This IC have built-in 4 channel BTL power amplifiers and 1 channel H-Bridge driver. Which drives focus-coil and tracking coil for 3-beam pick-up head, disc motor, feed motor and loading motor.
Featuers
· 4 channel BTL linear drivers High output power: Vout = 5.1 Vp-p (VCC = 8 V, RL = 8 Ω) Stand-by switch for BTL drivers 1 channel H-Bridge: VCE (H) + VCE (L) = 1.3 V (VR = VM = 8 V, IO = 200 mA) Logic control (forward, revers, brake, stand-by) Punch through current restriction diode for H-bridge 5 V regulator reference amp (with external output Tr.
