FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
voltage is out of regulation. In this case the RESET pin is
pulled low.
The RESET output can only be used in non-isolated
applications.
There is a 20
s delay filter preventing erroneous RESET
output pulses. During soft-start, RESET is held low. RESET
is released when the PWM controller is in regulation.
N-CHANNEL MOSFET GATE DRIVER
GATE drives an N-channel MOSFET. GATE sources and
sinks large transient currents up to 1.0 A to charge and
discharge the MOSFET gate. The GATE output is supplied
by the internal generated VDD voltage, which is internally set
to approximately 9.0 V.
For Power-over-Ethernet applications, the used MOSFET
must be able to withstand a DC level of ~60 V plus the
reflected voltage at the primary side of the transformer. This
requires a MOSFET rated at 150 V or 200 V.
