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.
