ON FAN3121T 2a low-voltage pmos-nmos bridge driver Datasheet

Features
Description


The FAN3268 dual 2 A gate driver is optimized to drive
a high-side P-channel MOSFET and a low-side Nchannel MOSFET in motor control applications
operating from a voltage rail up to 18 V. The driver has
TTL input thresholds and provides buffer and level
translation functions from logic inputs. Internal circuitry
provides an under-voltage lockout function that
prevents the output switching devices from operating if
the VDD supply voltage is below the operating level.
Internal 100 kΩ resistors bias the non-inverting output
low and the inverting output to VDD to keep the external
MOSFETs off during startup intervals when logic control
signals may not be present.

The FAN3268 driver incorporates MillerDrive™
architecture for the final output stage. This bipolarMOSFET combination provides high current during the
Miller plateau stage of the MOSFET turn-on / turn-off
process to minimize switching loss, while providing railto-rail voltage swing and reverse current capability.
The FAN3268 has two independent enable pins that
default to on if not connected. If the enable pin for noninverting channel A is pulled low, OUTA is forced low; if
the enable pin for inverting channel B is pulled low,
OUTB is forced high. If an input is left unconnected,
internal resistors bias the inputs such that the external
MOSFETs are off.

Typical Performance Characteristics
Input Thresholds
VDD
The FAN3268 driver has TTL input thresholds and
provides buffer and level translation functions from logic
inputs. The input thresholds meet industry-standard
TTL-logic thresholds, independent of the VDD voltage,
and there is a hysteresis voltage of approximately 0.4 V.
These levels permit the inputs to be driven from a range
of input logic signal levels for which a voltage over 2 V
is considered logic high. The driving signal for the TTL
inputs should have fast rising and falling edges with a
slew rate of 6 V/µs or faster, so a rise time from 0 to
3.3 V should be 550 ns or less. With reduced slew rate,
circuit noise could cause the driver input voltage to
exceed the hysteresis voltage and retrigger the driver
input, causing erratic operation.

Figure 27. MillerDrive™ Output Architecture
Static Supply Current
In the IDD (static) typical performance characteristics
(see Figure 6), the curve is produced with all inputs /
enables floating (OUT is low) and indicates the lowest
static IDD current for the tested configuration. For other
states, additional current flows through the 100 kΩ
resistors on the inputs and outputs shown in the block
diagram (see Figure 3). In these cases, the actual static
IDD current is the value obtained from the curves plus
this additional current.
MillerDrive™ Gate Drive Technology
FAN3268 gate drivers incorporate the MillerDrive™
architecture shown in Figure 1. For the output stage, a
combination of bipolar and MOS devices provide large
currents over a wide range of supply voltage and
temperature variations. The bipolar devices carry the
bulk of the current as OUT swings between one and two
thirds VDD and the MOS devices pull the output to the
high or low rail.
The purpose of the MillerDrive™ architecture is to
speed up switching by providing high current during the
Miller plateau region when the gate-drain capacitance of
the MOSFET is being charged or discharged as part of
the turn-on / turn-off process.
For applications with zero voltage switching during the
MOSFET turn-on or turn-off interval, the driver supplies
high peak current for fast switching even though the
Miller plateau is not present. This situation often occurs
in synchronous rectifier applications because the body
diode is generally conducting before the MOSFET is
switched on.
The output pin slew rate is determined by VDD voltage
and the load on the output. It is not user adjustable, but
a series resistor can be added if a slower rise or fall
time at the MOSFET gate is needed.
Under-Voltage Lockout
Internal circuitry provides an under-voltage lockout
function that prevents the output switching devices from
operating if the VDD supply voltage is below the
operating level. When VDD is rising, but below the 3.9 V
operational level, internal 100 kΩ resistors bias the noninverting output low and the inverting output to VDD to
keep the external MOSFETs off during startup intervals
when logic control signals may not be present. After the
part is active, the supply voltage must drop 0.2 V before
the part shuts down. This hysteresis helps prevent
chatter when low VDD supply voltages have noise from
the power switching.
VDD Bypass Capacitor Guidelines
To enable this IC to turn a device on quickly, a local highfrequency bypass capacitor CBYP with low ESR and ESL
should be connected between the VDD and GND pins
with minimal trace length. This capacitor is in addition to
bulk electrolytic capacitance of 10 µF to 47 µF commonly
found on driver and controller bias circuits.
A typical criterion for choosing the value of CBYP is to
keep the ripple voltage on the VDD supply to ≤5%. This
is often achieved with a value≥20 times the equivalent
load capacitance CEQV, defined here as QGATE/VDD.
Ceramic capacitors of 0.1 µF to 1 µF or larger are
common choices, as are dielectrics, such as X5R and
X7R, with good temperature characteristics and high
pulse current capability.
If circuit noise affects normal operation, the value of
CBYP may be increased to 50-100 times the CEQV or
CBYP may be split into two capacitors. One should be a
larger value, based on equivalent load capacitance, and
the other a smaller value, such as 1-10 nF mounted
closest to the VDD and GND pins to carry the higher
frequency components of the current pulses. The
bypass capacitor must provide the pulsed current from
both of the driver channels and, if the drivers are
switching simultaneously, the combined peak current
sourced from the CBYP would be twice as large as when
a single channel is switching.

Applications Information
Operational Waveforms
The FAN3268 gate driver incorporates fast-reacting
input circuits, short propagation delays, and powerful
output stages capable of delivering current peaks over
2 A to facilitate voltage transition times from under 10ns
to over 150 ns. The following layout and connection
guidelines are strongly recommended:
Figure 28 shows startup waveforms for non-inverting
channel A. At power-up, the driver output for channel A
remains low until the VDD voltage reaches the UVLO turnon threshold, then OUTA operates in-phase with INA.

VDD
UVLO
Turn-on threshold
Keep high-current output and power ground paths
separate from logic and enable input signals and
signal ground paths. This is especially critical when
dealing with TTL-level logic thresholds at driver
inputs and enable pins.
INA

Keep the driver as close to the load as possible to
minimize the length of high-current traces. This
reduces the series inductance to improve highspeed switching, while reducing the loop area that
can radiate EMI to the driver inputs and
surrounding circuitry.
OUTA

If the inputs to a channel are not externally
connected, the internal 100 kΩ resistors indicated
on block diagrams command a low output (channel
A) or a high output (channel B). In noisy
environments, it may be necessary to tie inputs or
enables of an unused channel to VDD or GND
using short traces to prevent noise from causing
spurious output switching.


Many high-speed power circuits can be susceptible
to noise injected from their own output or other
external sources, possibly causing output retriggering. These effects can be obvious if the
circuit is tested in breadboard or non-optimal circuit
layouts with long input, enable, or output leads. For
best results, make connections to all pins as short
and direct as possible.
The turn-on and turn-off current paths should be
minimized.
Figure 28. Non-Inverting Startup Waveforms
Figure 29 illustrates startup waveforms for inverting
channel B. At power-up, the driver output for channel B
is tied to VDD through an internal 100 kΩ resistor until
the VDD voltage reaches the UVLO turn-on threshold,
then OUTB operates out of phase with INB.

FAN3268 —2 A Low-Voltage PMOS-NMOS Bridge Driver
Layout and Connection Guidelines
Gate drivers used to switch MOSFETs and IGBTs at
high frequencies can dissipate significant amounts of
power. It is important to determine the driver power
dissipation and the resulting junction temperature in the
application to ensure that the part is operating within
acceptable temperature limits.
The total power dissipation in a gate driver is the sum of
two components, PGATE and PDYNAMIC:
PTOTAL=PGATE + PDYNAMIC
(1)
Gate Driving Loss: The most significant power loss
results from supplying gate current (charge per unit
time) to switch the load MOSFET on and off at the
switching frequency. The power dissipation that
results from driving a MOSFET at a specified gatesource voltage, VGS, with gate charge, QG, at
switching frequency, fSW , is determined by:
PGATE=QG • VGS • fSW • n
(2)
where n is the number of driver channels in use
(1 or 2).
As an example of a power dissipation calculation,
consider an application driving two MOSFETs with a
gate charge of 60 nC with VGS=VDD=7 V. At a switching
frequency of 500 kHz, the total power dissipation is:
PGATE=60nC • 7V • 500kHz • 2=0.42W
(5)
PDYNAMIC=3mA • 7V • 2=0.042W
(6)
PTOTAL=0.46W
(7)
The SOIC-8 has a junction-to-board thermal
characterization parameter of ψ JB=43°C/W. In a system
application, the localized temperature around the device
is a function of the layout and construction of the PCB
along with airflow across the surfaces. To ensure
reliable operation, the maximum junction temperature of
the device must be prevented from exceeding the
maximum rating of 150°C; with 80% derating, TJ would
be limited to 120°C. Rearranging Equation 4 determines
the board temperature required to maintain the junction
temperature below 120°C:
TB=TJ - PTOTAL • ψ JB
(8)
TB=120°C – 0.46W • 43°C/W=100°C
(9)
Dynamic Pre-drive / Shoot-through Current: A
power loss resulting from internal current
consumption under dynamic operating conditions,
including pin pull-up / pull-down resistors, can be
obtained using the “IDD (No-Load) vs. Frequency”
graphs in Typical Performance Characteristics to
determine the current IDYNAMIC drawn from VDD
under actual operating conditions:
PDYNAMIC=IDYNAMIC • VDD • n
(3)
Once the power dissipated in the driver is determined,
the driver junction rise with respect to circuit board can
be evaluated using the following thermal equation,
assuming ψ JB was determined for a similar thermal
design (heat sinking and air flow):
TJ
=PTOTAL • ψ JB + TB
(4)
where:
TJ =driver junction temperature
ψ JB =(psi) thermal characterization parameter relating
temperature rise to total power dissipation
TB =board temperature in location defined in
Note 2 under Thermal Resistance table.
