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.
