01W109A 4-channel BTL driver BA5824FP Dimension (Units : mm) 18.5 ± 0.2 15 0.5 ± 0.2 9.9 ± 0.3 28 7.5 ± 0.2 Description BA5824FP incorporates 4-channel drivers that operate the motor and the 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. The input of CH4 can be switched by the control pin. 1 14 Features 1) Wide dynamic range 2) Built-in thermal shut down circuit 3) Built-in mute function by control pin and mute pin 0.11 2.2 ± 0.1 5.15 ± 0.1 0.8 0.35 ± 0.1 0.08 M 16.0 ± 0.2 0.25 ± 0.1 0.1 S HSOP28 Applications CD players, DVD players CD players, and DVD players for Car Absolute Maximum Ratings (Ta=25°C) Parameter Symbol Limits Unit Vcc 18 V Maximum applied voltage Power dissipation Operating temperature range Pd Topr Storage temperature range Tstg 1700 * –35 ~ –55 ~ +85 +150 mW °C °C *Derating : 13.6mW/°C for operation above Ta=25°C November, 2001 Recommended Operating Conditions (Ta=25°C) Parameter Symbol Min.
