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.
