描述 Description

Bipolar Liner Integrated Circuit Silicon MonolithicTA2125AF 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.

特性 Features

• 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 to 9.0 V
