Frequently Asked Questions
What is the typical PWM control frequency?
The AN8011S supports a PWM control frequency of 500 kHz.
How can I set the dead-time period for the outputs?
For both channels, the dead-time period (DTC) can be set by connecting an external resistor to pins 6 (DTC2) and 11 (DTC1).
Where does the power supply voltage need to be connected?
The main power supply voltage is applied to pin 9 (V_CC).
Does the IC have built-in protection features?
Yes, it incorporates circuits for short-circuit protection and Under-Voltage Lockout (U.V.L.O.).
