DESCRIPTION
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. The FAN322X 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 FAN3226 offers two inverting drivers and the FAN3227 offers two non−inverting drivers. Each device has dual independent enable pins that default to ON if not connected. In the FAN3228 and FAN3229, each channel has dual inputs of opposite polarity, which allows configuration as non−inverting or inverting with an optional enable function using the second input.
