TA2125AF Datasheet | Toshiba

Preliminary TOSHIBA Bipolar Liner Integrated Circuit Silicon Monolithic 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: 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 m A) 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.) - - - - - Block Diagram 4ch Driver REG RIN FIN STB IN3 IN4 STB VCC RL4 REG OUT 36 35 34 33 STBY 32 31 30 STBY 29 28 FIN 27 26 25 N.C. 24 23 ´3 22 21 20 19 RL3 Control Logic ´ 3 ´ 3 ´ 3 Iref ´ 3 10 11 12 13 14 15 ´ 3 ´ 3 ´ 3 16 17 18 2 RL5 FIN GND N.C.
