00W097A 4-channel BTL driver for car CD players BA5993FP Description Dimension (Units : mm) 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. 18.5±0.2 1 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 0. 1 1 2.2±0. 1 Features 5.15±0. 1 0.8 0.25±0. 1 9.9±0.3 15 7.5±0.2 28 14 0.35±0. 1 0.3Min. 0. 15 HSOP28 Applications Car CD players Absolute Maximum Ratings (Ta=25°C) Symbol Limits Power supply voltage Vcc 18 Power dissipation Pd Parameter 1700 Unit V * mW Operating temperature range Topr –35 ~ +85 Storage temperature range Tstg –55 ~ +150 °C °C * Derating : 13.6mW/°C for operation above Ta=25°C Recommended Operating Conditions (Ta=25°C) Parameter Power supply voltage Symbol Min.
