The FAN3213 series of dual-channel 4-A gate drivers is designed to drive N-channel enhancement mode MOSFETs in driving low-side switching applications by supplying high peak current pulses during short switching intervals. Both provide TTL input thresholds. Internal circuitry provides an undervoltage lockout by holding the output low until the supply voltage enters the operating range. Additionally, these drivers provide matched internal propagation delays between the A and B channels, making them suitable for dual gate drive applications that require tight timing, such as synchronous rectifiers. This allows two drivers to be connected in parallel, effectively doubling the current capability to drive a single MOSFET. The FAN3213/14 drivers incorporate the MillerDrive architecture for the final output stage. This combination of bipolar MOSFETs provides high current during the Miller plateau of the MOSFET on/off process to minimize switching losses while providing rail-to-rail voltage swing and reverse current capability. The FAN3213 has two inverting drivers and the FAN3214 has two non-inverting drivers. Both offer standard 8-pin SOIC encapsulation.
