Nee .. bestimmt nicht, aber der FAN klemmt intern selber ...
Zitat:2-5. Output Drive;deal2
The FAN7527 contains a single totem-pole output stage
designed specifically for a direct drive of power MOSFET.
The drive output is capable of up to 500mA peak current
with a typical rise and fall time of 130ns, 50ns respectively
with a 1.0nF load. Additional circuitry has been added to
keep the drive output in a sinking mode whenever the UVLO
is active. This characteristic eliminates the need for an
external gate pull-down resistor. Internal voltage clamping
ensures that the output driver is always lower than 14V when
supply voltage exceeds the rated Vgs of the external
MOSFET. This eliminates an external zener diode and extra
power dissipation associated with it that otherwise is
required for the reliable circuit operation.
