Description
The FAN3216 and FAN3217 dual 2A gate drivers are
designed
= 12V
MOSFETs
providing high peak current pulses during the short
= 6V
OUT
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.
