Function
Switching node. SW is the switching node. This is the return for the high-side MOSFET drive. Connect
SW to the high-side MOSFET source and the low-side MOSFET drain.
Boosted drive input for high side gate driver. BST supplies power to the high-side MOSFET gate driver
allowing the gate drive voltage higher than the input voltage for full enhancement of the high-side MOSFET. Connect the boost capacitor between SW and BST, and connect a diode from VCC to BST to charge
the boost capacitor.
Input supply voltage. Connect VCC to the 5V bias supply voltage. Bypass VCC to GND with a 1μF or
greater capacitor as close to the AAT4910 as possible.
Ground.
Low-side MOSFET gate drive output. DL drives the gate of the low-side MOSFET. Connect the gate of the
low-side MOSFET to DL.
Logic signal input. The state of IN determines if the high-side or low-side switch is on/off. Drive IN high
to turn on the high-side switch, drive IN low to turn on the low-side switch.
Enable input. Drive EN high to turn on the AAT4910, drive it low to turn it off. When EN is low, both DH
and DL are driven low to turn off the external MOSFETs. For automatic operation, connect EN to VCC.
High-side MOSFET gate drive output. DH drives the gate of the high side MOSFET. Connect the gate of
the high-side MOSFET switch to DH.

Functional Description
The AAT4910 is a dual MOSFET driver that takes a logic
input (IN) and drives both high and low-side N-channel
MOSFETs. It can be used to drive the power section of
DC/DC converters, Class D audio power amplifiers, or
other high-power devices requiring switched voltage.
The device is powered from a 5V rail and includes circuitry to drive the high-side N-channel MOSFET with up
to 28V power input. When driven low, the enable input
(EN) turns off the driver and reduces the operating current to less than 1μA. Over-temperature shutdown protects the AAT4910 in the case of a short circuit or defective MOSFET. High-side driver under-voltage lockout
turns off the high-side MOSFET when there is insufficient
voltage to drive the MOSFET preventing damage at
startup or if the IN input is held high continuously.
High-Side/Low-Side MOSFET Driver
The AAT4910 turns on the high-side external MOSFET
when IN is driven high, and turns on the low-side
MOSFET when IN is driven low. The low 3Ω pull-up and
1.7Ω pull-down resistance allow fast turn-on and turn-off
times and/or the capability to drive multiple large
MOSFETs. The lower pull-down resistance ensures that
the MOSFETs remain off during fast drain-voltage switching transients.
8
The high-side driver powers the gate of the external
MOSFET to a voltage greater than the input, allowing it
to fully turn on without a separate power supply rail. The
high-side driver boost capacitor between SW and BST is
charged when the low-side MOSFET is on via the 5V
power source and the external rectifier. Once the capacitor is charged, the DH MOSFET gate driver output is
powered from BST, allowing sufficient MOSFET gate voltage for full enhancement. An under-voltage lockout feature on the BST-to-SW voltage turns off the DH output if
the voltage falls below the under-voltage threshold. This
ensures that should the boost capacitor excessively discharge or is not able to fully charge, the MOSFET will not
be driven to an intermediate state that would result in
excessive power dissipation and could cause the MOSFET
to fail.
High-to-low and low-to-high transitions include a breakbefore-make “dead” time when both MOSFETs are turned
off. This insures that one MOSFET is fully turned off
before the other MOSFET is turned on to prevent the
possibility of shoot-through current.
Thermal overload protection turns off the AAT4910
should the die temperature exceed the 140°C threshold.
This protects the AAT4910 from high ambient temperature conditions and MOSFET failures. At 15°C hysteresis
prevents rapid cycling in and out of thermal shutdown.

DATA SHEET
AAT4910
28V Half-Bridge Dual N-Channel MOSFET Driver
Application Information
Supply Capacitor
The input capacitor provides a low impedance loop for
the edges of pulsed current drawn by the AAT4910. A
4.7µF to 10µF X7R or X5R low ESR/ESL ceramic capacitor selected for the input is ideal for this function. To
minimize tray resistance, the capacitor should be placed
as closely as possible to the input pin in order to minimize EMI and input voltage ripple.
Bootstrap Capacitor
In order to fully turn on the high side external MOSFET
while the low side MOSFET turns OFF, a bootstrap capacitor is connected between the BST pin and the SW pin.
This capacitor is charged up to VCC through an external
diode when the low side MOSFET is ON. The boost strap
capacitor voltage rating should be able to withstand at
least twice the maximum voltage supply, and its value
should be at least fifteen times larger than the gate
capacitor value. The bootstrap capacitance can be estimated by Equation 1:
Eq. 1: CBST(MIN) = 15 ·
QGATE
VCC - VDIODE
For example, a Si4908DY dual N-channel MOSFET has a
total gate charge of QGATE = 6nC at VGS = 5V. Using VCC =
5V and VDIODE = 1V, then
CBST(MIN) = 15 ·
6nC
= 0.04µF
5V - 1V
A 0.1µF/12V low ESR X7R ceramic capacitor is selected
to handle twice the maximum supply voltage (5.5V) and
to prevent voltage transient at the drain of the high side
MOSFET.
Shoot-Through Protection
The high-side and low-side MOSFETs of the AAT4910
cannot conduct at the same time in order to prevent
shoot-through current. When the clock pulse at IN pin
rises, DL is first pulled down. The shoot-through protection circuit waits for about 60ns before pulling up DH.
Similarly, when the clock pulse goes low, DH is pulled
down first, and the circuit pulls up DL after about 40ns.
In this way, the high-side and low-side MOSFETs are
never turned on at the same time to prevent the supply
voltage shorts to ground. The time between the DH and
DL pulses should be kept as short as possible to minimize current flows through the body diode of the lowside MOSFET(s). The break-before-make shoot-through
protection significantly reduces the losses associated
with the driver at high frequency.
Output Inductor Selection
A 2.2μH to 10μH inductor value with appropriate DCR is
selected to maintain the peak inductor current below the
maximum current of the high-side and low-side MOSFETs.
The peak inductor current, which varies according to the
driving frequency (PWM), should not exceed the inductor
saturation current. In application where the driving frequency below 100KHz, a 4.7μH to 10μH inductor should
be used to avoid the peak inductor current exceeding the
maximum current of the MOSFETs.
Thermal Calculations
The power dissipation of the AAT4910 MOSFETs driver
includes power dissipation in the MOSFETs due to charging and discharging the gate capacitance, quiescent current power dissipation, and transient power in the driver
during output transitions (the transient power is usually
very small and losses in it can be neglected). The maximum package power dissipation can be estimated by
Equation 2:
Eq. 2: PD(MAX) = VCC · IIN =
TJ(MAX) - TA
qJA
= IQ · VCC + QG(HS)FSW · VCC + QG(LS)FSW · VCC
Where:
TJ(MAX) is the junction temperature of the dice (C°).
TAMB is the ambient temperature (C°).
qJA =160 °C/W is the thermal resistance (C°/W).
IQ is the operating current of the driver (mA).
QG(HS) and QG(LS) are the gate charge of high side and low
side MOSFET (nC).
FSW is the switching frequency (MHz).
The maximum junction temperature can be derived from
Equation 2 for the SC70JW-8 package:
Eq. 3: TJ(MAX) = PD(MAX) · qJA + TAMB

PTOTAL = 5V · 450μA + 2(5V · 6nC · 100kHz) = 8.25mW
The maximum junction temperature at 100kHz is determined by Equation 3:
TJ(MAX) = 8.25mW · 160 °C/W + 85 °C = 86.3°C
This is well within the thermal limits for safe operation
of the device.
Gate Drive Current Ratings
Assuming the maximum gate charge of high side and
low side MOSFET are equal to each other, the maximum
gate drive capability for the designed maximum junction

from Equation 2:

Typical Applications
Multi-Phase Synchronous Buck Converter
The most common AAT4910 applications include multiphase DC/DC converter output power stages, DC motor
drive, and Class D audio power amplifier. Figure 2 shows
a typical configuration when used as a 2-phase buck
converter power stage with synchronous rectification.
The EN pin can be used to force the LX output to a high
impedance state which enables the output inductor to
operate in discontinuous conduction mode (DCM) in
order to improve the efficiency under light load conditions. The body diode associated with the low side
switching MOSFET gives the AAT4910 inductive switching capability, and clamps the LX node at one diode drop
below GND during the break-before-make time. The
multiphase buck converter assures a stable and high
performance topology for high currents and low voltages
which are demanded in desktop computers, workstations, and servers. Figure 3 shows an output ripple current reduction due to 2-phase cancellation.

Class D Audio Amplifier
The AAT4910 is also ideally suited for use as an efficient
output driver for a Class D audio amplifier. In this type
of amplifier, the switches are either fully on or fully off,
significantly reducing conduction losses in the output
power devices. In this way, Class D audio offers a superior efficiency over 90%, which can not be achieved with
traditional Class AB audio. A typical Class D audio amplifier block diagram is illustrated in Figure 5, in which the
audio signal is modulated by the PWM carrier signal
which drives the IN terminal of the AAT4910. A low pass
filter (L1, C1) at the last stage removes the high frequency of the PWM carrier signal. Typically, a 1000µF DC
blocking capacitor (C2) is used at the output to provide
DC short circuit protection.

The AAT4910 is also ideally suited for use as an efficient
output driver for DC brushless motor control. The inductive load switching capability of the AAT4910 eliminates
the need for external diodes. A typical half-bridge motor
control circuit is illustrated in Figure 4. In half-bridge
motor control, one end of the motor is connected to the
SW node of the driver, and the other end is connected to
the power supply or ground. The speed of the motor is
controlled by the PWM duty cycle at the IN terminal of
the AAT4910. When the high-side MOSFET turns OFF and
the low-side MOSFET turns ON, the current flows through
the motor to ground from the supply voltage (blue
arrow). During the ON time, the low-side MOSFET turns
OFF and the high-side MOSFET turns ON. The winding

Layout
The suggested PCB layout for the AAT4910 is shown in
Figures 7 and 8. The following guidelines should be used
to help ensure a proper layout.
1. Place the driver as close as possible to the MOSFETs.
2. Place the decoupling capacitor C3 as close as possible to the VCC and GND pins.
2. DH, LX, DL, and GND should connect as closely as
possible to the MOSFETs to minimize propagation
delay.
4. The high-current loop between the high-side and
low-side MOSFETs and the input capacitor should be
kept as small as possible.
5. The trace connected to the drain and source MOSFETs
should be large to improve heat dissipation.
