Power Driver IC for CD Player

Bipolar Liner Integrated Circuit Silicon Monolithic

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.

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
