| 00W097A 4-channel BTL driver for car CD players BA5993FP Description The BA5993P incorporates 4-channel drivers that operate the motor and actuator for car CD players. CH1, 2, and CH3, 4 each have power supply independently. The highly efficient drive can be achieved due to the low voltage operation. 9.90.3 7.50.2 Dimension (Units : mm) 18.50.2 28 15 Features 2.20. 1 1 5.150. 1 14 0. 1 1 0.8 0.350. 1 0.3Min. 0. 15 1) Built-in 3.3V regulator 2) Built-in standard operational amplifier 3) Built-in mute function 3 lines (CH1,2, CH3 and CH4) 4) Reference voltage can be changed into external input voltage and internal voltage. 5) Built-in thermal shut down circuit HSOP28 Applications Car CD players Absolute Maximum Ratings (Ta=25C) Parameter Power supply voltage Power dissipation Operating temperature range Storage temperature range Symbol Vcc Pd Topr Tstg -35 -55 Limits 18 1700 ~ ~ * Unit V mW +85 +150 C C * Derating : 13.6mW/C for operation above Ta=25C Recommended Operating Conditions (Ta=25C) Parameter Power supply voltage Symbol VCC Min. 6 Typ. -- Max. 14 Unit V (When the regulator is not used ; 4.5~14V) October, 2000 0.250. 1 Electrical characteristics (Unless otherwise noted; Ta=25C, Vcc=8V, BIAS=1.65V, RL=8 ) Parameter Current consumption (No signal) Output offset voltage Maximum output voltage (CH1,2) Maximum output voltage (CH3,4) Voltage gain (CH1,2,3) Voltage gain (CH4) Regulator output voltage Op-amp. offset voltage Op-amp. high level voltage Op-amp. low level voltage Symbol IQ Voof VOM1 VOM2 GVC1 GVC4 VREG VOFOP VOHOP VOLOP Min. -- -50 5.0 5.7 15.5 21.5 15.5 3.0 -6 7.5 -- Typ. 15 0 5.6 6.3 17.5 23.5 17.5 3.3 0 7.9 0.1 Max. 23 50 -- -- 19.5 25.5 19.5 3.6 6 -- 0.3 Unit mA mV V V dB dB dB V mV V V VIN=0.5V, BCONT='H' VIN=0.2V, BCONT='H' VIN=0.2V, BCONT='L' IREG=25mA Conditions Application Circuit MUTE1 MUTE4 TRAVERSE MUTE3 BIAS CONTROL 0.1mF 0.1mF + + + - mCOM SERVO LOADING TRAVERSE BIAS Loading motor Traverse motor M 28 27 26 CH3 MUTE CONTROL M 17 16 15 10k 25 24 23 22 PreVcc 21 Vcc 20 CH4 MUTE 20k 19 GND 18 10k 10k 10k + - + - + + BIAS 10k 10k 10k 10k 10k 1.65V 10k 10k 20k + LEVEL SHIFT + T.S.D LEVEL SHIFT BA5993FP 10k + - LEVEL SHIFT 20k 10k + 20k 2.5V LEVEL SHIFT 10k 10k 10k PreVcc + 10k 30k PreGND 10k + + Vcc CH1,2 MUTE GND 10k 10k 10k 10k 1 2 3 4 5 6 1mF 7 8 9 10 11 12 13 14 FOCUS 0.1mF 47mF Tracking coil Focus coil TRACKING 3.3V REGULATOR OUT |
