The following chapter describes the behavior and characteristic of the input pin.
5.1
Figure 4
The internal circuitry is powered via the input pin. During normal operation the input is connected to the gate of
the power MOSFET. The current handling capability of the driving circuit does not influence the device behavior
as long as the supply current
During PWM operation the recharging of the gate increases the current consumption to the level
Figure 4
The current sink to ground ensures that the channel switches off in case of an open input pin.
The Zener diode protects the input circuit against ESD pulses.
