1. Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. 2. The accuracy of JA or power dissipation will be based on PC board layout. 3. The maximum continuous output current should be set due to be corresponding with the power dissipation. 4. Device are ESD sensitive. Handling precaution recommended. The Human Body model is a 100pF capacitor discharged through a 1.5K resistor into each pin.

FIG. 3: DIP-16 package of AT5562 for application with a turbo function.
NOTEDTo see below figure. Because DCM 1 is operated with turbo function, D1A pin (pin 9) must be connected to voltage at VTURBO. The output current is essentially continuous due to inductor -characteristic of motor, so if DCM1 is operated in reverse-forward, the stop mode which will make AT5562 to turn off all switcher should not be the way to stop the DCM1. The brake mode which will make AT5562 turn on Q1 and Q3 is best way to stop motor in reverseforward mode.
