BA (extended Blanking & Auto-restart)
The BA pin combines the functions of extendable
blanking time for over load protection and the external
auto-restart enable. The extendable blanking time
function is to extend the built-in 20 ms blanking time by
adding an external capacitor at BA pin to ground. The
external auto-restart enable function is an external
access to stop the gate switching and force the IC enter
auto-restart mode. It is triggered by pulling down the
BA pin to less than 0.33V.
FB (Feedback)
The information about the regulation is provided by the
FB Pin to the internal Protection Unit and to the internal
PWM-Comparator to control the duty cycle. The FB-
Signal is the only control signal in case of light load at
the Active Burst Mode.
CS (Current Sense)
The Current Sense pin senses the voltage developed
on the series resistor inserted in the source of the
integrated CoolMOS
internal threshold of the Current Limit Comparator, the
Driver output is immediately switched off. Furthermore
the current information is provided for the PWM-
Comparator to realize the Current Mode.
Drain (Drain of integrated CoolMOS
Drain pin is the connection to the Drain of the
integrated CoolMOS
VCC (Power Supply)
VCC pin is the positive supply of the IC. The operating
range is between 10.5V and 25V.
GND (Ground)
GND pin is the ground of the controller.
