Features
General Description
• Independent 2-channel H-bridge drivers built-in
power PMOS and NMOS.
• All the drivers with forward, reverse, stop and
brake function.
• Low stand-by and operating current.
• Low on-resistance. (1.0 Ω )
• Low voltage operation.
• Built-in thermal shutdown function.
• Package PDIP-16 & SOP-14

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 θJA 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 1.5KΩ resistor into each pin.

FIG. 3: DIP-16 package of AT5562 for application with a turbo function.
NOTED:To 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.
