Typical Application of AM5669 in DVD Player Mar. 2007 Rev. 1. 2 BCD Semiconductor Manufacturing Limited 11 Preliminary Datasheet 5-CHANNEL MOTOR DRIVER FOR DVD PLAYER AM5669 Application Information 6. Tray driver logic input: 1. The built-in thermal shutdown circuit mutes the output current when the chip temperature reaches 175oC (Typ). The hysteresis is set to 30oC (Typ), so the circuit will start up again when the chip temperature falls to 145oC (Typ). 2. In case mute pin voltage is under 0.5V or this pin is not connected, output current is muted (except for tray motor driver). Mute pin voltage should be more than 2.0V for normal application. 3. Bias pin (pin 27) should be pulled up to more than 1.2V. In case the bias pin voltage is pulled down below 0.9V (Typ), the output current is muted. FWD (pin6) REV (pin7) VOTR+ (pin10) VOTR(pin9) Function L L OPEN OPEN Open mode L H L H Reverse mode H L H L Forward mode H H L L Brake mode Input circuit of pins 6 and 7 is designed to avoid simultaneous activation of upper and lower output tray; however, in order to improve reliability, apply motor forward/reverse input once through open mode. We recommend time period for open longer than 10msec. 4. Insert the bypass capacitor (about 0.1µF) between VCC1,2 pin and GND pin as close as possible to this chip. "H" side output voltage on output pins (VOTR+ or VOTR-) varies depending on output control terminal for tray (pin 21). "H" side output voltage is set to three times (9.2dB Typ) the voltage of VCTL (pin 21). And, "L" side output voltage is equal to output saturation voltage. 5. Heat dissipation fins are attached to the GND on the inside of the package. Make sure to connect them to the external GND.
