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 )
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.)

Precaution Use
(4ch BTL)
· Input stage
Minimum input DC voltage range for buffer is 0.2 V
· Driver stage
Each channel driver consists of BTL configuration linear amplifier.
Voltage gain is fixed: Gv = 15.2dB
· VCIN terminal
VCIN is reference voltage terminal for input signal
· GND
Pin 8~10 and Pin 27~29 are connected to FIN through inner lead frame.
Each FIN are not connected each other also.
The heat of power dissipation is transferred to PCB, through PW-GND Pin. PW GND is connected to substrate of
Pellet to connected copper foil area as large as possible.
· VCC1/VCC2
Pin 14 and pin 23 are not connected through AL layer on chip.
(H-Bridge)
· VR/VM terminal
VR terminal is control for H-brige dynamic range. I36 = 30 mA (Brake Mode)
VM terminal is VCC terminal for H-Bridge.
· STBY/REG STBY
STBY is standby control terminal for 4ch BTL.
REG STBY is standby control terminal for regulator.
