TA2125AF
Power Driver IC for CD Player
TA2125AF
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.)
· Thermal shut down protection
· Operating supply voltage range: VCC = 5.0-9.0 V
Weight: g (typ.)
