The FAN3216 and FAN3217 dual 2 A gate drivers are designed to
drive N−channel enhancement−mode MOSFETs in low−side
switching applications by providing high peak current pulses during
the short sw itching 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, the drivers feature matched internal
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.
