Preliminary ^{TOSHIBA Bipolar Liner Integrated Circuit Silicon Monolithic}

TA2125AF

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: V = 5.1 Vp-p (V

= 8 V, R = 8 Ω)

out CC

Stand-by switch for BTL drivers

1 channel H-Bridge: V + V

= 1.3 V (V = V = 8 V,

R M

CE (H) CE (L)

Weight:

g (typ.)

= 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: V

= 5.0-9.0 V
