Data Sheet 5-CHANNEL MOTOR DRIVER PLAYER Application Information
built-in thermal shutdown circuit mutes output current when chip temperature reaches 175oC (Typ). hysteresis 30oC (Typ), circuit will start again when chip temperature falls 145oC (Typ). Input circuit pins designed avoid simultaneous activation upper lower output tray; however, order improve reliability, apply motor forward/reverse input once through open mode. Time period open recommended longer than 10msec. side output voltage output pins (VOTR+ VOTR-) varies depending output control terminal tray (pin 21). side output voltage three times (9.2dB Typ) voltage VCTL (pin 21). And, side output voltage equal output saturation voltage. 3.3V system, voltage applied VCCD (pin lower than detector threshold voltage (Typ 2.9V), RESET (pin will generate level reset signal. Once VCCD comes over 3.1V, RESET will change level immediately.

case mute voltage under 0.5V this connected, output current muted (except tray motor driver). Mute voltage should more than 2.0V normal application.
BIAS (pin should pulled more than 1.2V. case bias voltage pulled down below 0.9V (Typ), output current muted.
Insert bypass capacitor (about 0.1µF) between VCC1,2 close possible this chip.
Heat dissipation fins attached inside package. Make sure connect them external GND.
