Dual 4A High-Speed, Low-Side Gate Drivers

Features

Description

The FAN3223-25 family of dual 4A gate drivers is

designed to drive N-channel enhancement-mode

MOSFETs in low-side switching applications by

providing high peak current pulses during the short

switching intervals. The driver is available with either

TTL or CMOS 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.

Industry-Standard Pinouts

4.5 to 18V Operating Range

5A Peak Sink/Source at V_DD= 12V

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

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 switching loss, while providing rail-

to-rail voltage swing and reverse current capability.

12ns / 9ns Typical Rise/Fall Times with 2.2nF Load

Typical Propagation Delay Under 20ns Matched

within 1ns to the Other Channel

Double Current Capability by Paralleling Channels

8-Lead 3x3mm MLP or 8-Lead SOIC Package

Rated from –40°C to +125°C Ambient

The FAN3223 offers two inverting drivers and the

FAN3224 offers two 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, which allows configuration

as non-inverting or inverting with 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 power

MOSFET OFF.
