Overview: Dual 2-A High-Speed, Low-Side Gate Drivers FAN3216 / FAN3217
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 MillerDrivet 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.
