Description
The FA N3223-25 family of dual 4 A gate dr ivers is
designed to drive N-channel enhancement- mode
MOSFETs in low -side sw itching applications by
providing high peak current pulses dur ing the short
sw itching intervals. The driver is available w ith either
TTL or CMOS input thresholds. Internal circuitry
provides an under-voltage lockout function by holding
the output LOW until the supply voltage is w ithin the
operating range. In addition, the drivers feature matched
internal propagation delays betw een A and B channels
for applications requiring dual gate drives w ith critical
timing, such as synchronous rectifiers. This also
enables connecting tw o drivers in parallel to effectively
double the current capability driving a single MOSFET.
The FA N322X drivers incorporate Miller Drive™
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 sw itching loss, w hile providing rail-
to-rail voltage sw ing and reverse current capability.
The FAN3223 offers two inverting drivers and the
FA N3224 offers tw o non-inverting drivers. Each device
has dual independent enable pins that default to ON if
not connected. In the FA N3225, each channel has dual
inputs of opposite polar ity, w hich allow s configuration as
non-inverting or inverting w ith an optional enable
function using the second input. If one or both inputs are
left unconnected, internal resistors bias the inputs such
that the output is pulled LOW to hold the pow er
MOSFET OFF.
