efficiency. This is done by reducing the switch on slope when reaching the MOSFET threshold. This is achieved by a
slope control of the rising edge at the driver’s output. The output driver is clamped by an internal 15V Zener diode in
order to protect power MOSFET transistors against undesirable gate over voltage.
