Description
The FAN3216 and FAN3217 dual 2A gate drivers are
designed
MOSFETs
providing high peak current pulses during the short
switching intervals. They are both available with TTL
input thresholds. Internal circuitry provides an under-
voltage lockout function by holding the output LOW until
the supply voltage is within the operating range. In
addition,
propagation delays between A and B channels for
applications requiring dual gate drives with critical
timing, such as synchronous rectifiers. This also
enables connecting two drivers in parallel to effectively
double the current capability driving a single MOSFET.
The FAN3216/17 drivers incorporate MillerDrive™
architecture for the final output stage. This bipolar-
MOSFET combination provides high current during the
Miller plateau stage of the MOSFET turn-on / turn-off
process to minimize switching loss, while providing rail-
to-rail voltage swing and reverse current capability.
The FAN3216 offers two inverting drivers and the
FAN3217 offers two non-inverting drivers. Both are
offered in a standard 8-pin SOIC package.
