ADP3413
GENERAL DESCRIPTION
PGND
The ADP3413 is a dual MOSFET driver optimized for driving
two N-channel MOSFETs which are the two switches in a
nonisolated synchronous buck power converter. Each of the
drivers is capable of driving a 3000 pF load with a 20 ns propa-
gation delay and a 30 ns transition time. One of the drivers can
be bootstrapped and is designed to handle the high voltage
slew rate associated with “floating” high side gate drivers.
The ADP3413 includes overlapping drive protection (ODP)
to prevent shoot-through current in the external MOSFETs.
The
OD
Pin provides high speed control to quickly turn off
both gate drives.
The ADP3413 is specified over the commercial temperature
range of 0°C to 70°C and is available in an 8-lead SOIC package.

NOTES
1
All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC) methods.
2
Logic inputs meet typical CMOS I/O conditions for source/sink current (~1
µA).
3
AC specifications are guaranteed by characterization but not production tested.
4
For propagation delays, “tpdh” refers to the specified signal going high; “tpdl” refers to it going low.
Specifications subject to change without notice.

PIN FUNCTION DESCRIPTIONS

Mnemonic

Function
Floating Bootstrap Supply for the Upper MOSFET. A capacitor connected between BST and SW Pins
holds this bootstrapped voltage for the high side MOSFET as it is switched. The capacitor should be
chosen between 100 nF and 1 F.
TTL-level input signal that has primary control of the drive outputs.
Output Disable. When low, this pin disables normal operation, forcing DRVH and DRVL low.
Input Supply. This pin should be bypassed to PGND with ~1
µF
ceramic capacitor.
Synchronous Rectifier Drive. Output drive for the lower (synchronous rectifier) MOSFET.
Power Ground. Should be closely connected to the source of the lower MOSFET.
This pin is connected to the buck-switching node, close to the upper MOSFET’s source. It is the floating
return for the upper MOSFET drive signal. It is also used to monitor the switched voltage to prevent turn-
on of the lower MOSFET until the voltage is below ~1 V. Thus, according to operating conditions, the
high low transition delay is determined at this pin.
Buck Drive. Output drive for the upper (buck) MOSFET.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the ADP3413 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
