Dual 4-A High-Speed, Low-SideGate Drivers

Features

Description

The FA N3223-25 family of dual 4 A gate drivers is

designed to drive N-channel enhancement-mode

MOSFETs in low -side sw itching applications by

providing high peak current pulses during 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.

Industry-Standard Pinouts

4.5-V to 18-V Operating Range

5-A Peak Sink/Source at V_DD=12 V

4.3-A Sink / 2.8-A Source at V_OUT=6 V

Choice of TTL or CMOS Input Thresholds

Three Versions of Dual Independent Drivers:

Dual Inverting + Enable (FAN3223)

Dual Non-Inverting + Enable (FAN3224)

Dual-Inputs (FAN3225)

Internal Resistors Turn Driver Off If No Inputs

MillerDrive™ Technology

The FAN322X drivers incorporate MillerDrive™

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.

12-ns / 9-ns Typical Rise/Fall Times (2.2-nF Load)

Under 20-ns Typical Propagation Delay Matched

w ithin 1 ns to the Other Channel

Double Current Capability by Paralleling Channels

8-Lead 3x3 mm MLP or 8-Lead SOIC Package

Rated from –40°C to +125°C Ambient

The FAN3223 offers two inverting drivers and the

FAN3224 offers tw o non-inverting drivers. Each device

has dual independent enable pins that default to ON if

not connected. In the FAN3225, each channel has dual

inputs of opposite polarity, 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.
