Texas Instruments (TI) (NASDAQ:TXN) today
introduced two new device families that help reduce
size and weight in motor drive applications. When used
together, DRV832x brushless DC (BLDC) gate drivers
and CSD88584/99 NexFET™ Power Blocks require as
little as 511 mm2, half the board space of competing
solutions.

The DRV832x BLDC gate drivers feature a smart gate-
drive architecture that eliminates up to 24 components
traditionally used to set the gate drive current while
enabling designers to easily adjust field-effect
transistor (FET) switching to optimize power loss and
electromagnetic compliance. The CSD88584Q5DC
and CSD88599Q5DC power blocks leverage two FETs
in a unique stacked-die configuration, which doubles
power density and minimizes the FET resistance and
parasitic inductances typically found in side-by-side FET
configurations.
An 18-volt compact BLDC motor reference design
demonstrates how the DRV8323 gate driver and
CSD88584Q5DC power block can drive 11 W/cm3
power and enable engineers to jump-start their designs
for smaller, lighter-weight power tools, integrated motor
modules, drones and more. For more information, visit
Benefits of using a CSD88584/99 and DRV832x device
together
Maximum power density: The combined solution delivers
700 W of motor power without a heat sink, providing
50 percent higher current than conventional solutions
without increasing the footprint.
High peak current: As demonstrated by the 18-volt BLDC
reference design, the smart gate driver and power block
are capable of driving a peak current of up to 160 A for
more than 1 second.
Optimal system protection: The combination enables
shorter trace lengths and actively prevents unintended
FET turn-on, while also providing undervoltage,
overcurrent and thermal protection.
Superior thermal performance: The CSD88584Q5DC
and CSD88599Q5DC power blocks come in TI’s
DualCool™ thermally enhanced package, which
enables designers to apply a heat sink to the top of the
device to decrease thermal impedance and increase the
amount of power dissipated to maintain safe operating
temperatures for the board and end application.
Clean switching: The power blocks’ switch-node clip
helps eliminate parasitic inductance between high- and
low-side FETs. Additionally, the DRV832x gate driver’s
passive component integration minimizes board traces.
Tools and support to jump-start design
In addition to the 18-volt BLDC motor reference design,
engineers can search for other motor reference designs
that use the power blocks and gate drivers to help solve
their system design challenges. The three-phase smart
gate-driver evaluation module (EVM) allows designers
to drive a 15-A, three-phase BLDC motor using the
DRV8323R gate driver, CSD88599Q5DC power block
and MSP430F5529 microcontroller LaunchPad™
development kit. The EVM is available from the TI store
for US$99.00.
Package, availability and pricing
The new DRV832x BLDC smart gate drivers offer
peripheral and interface options for engineers to select
the best device for their design: with or without an
integrated buck regulator or three integrated current-
shunt amplifiers. Each device option is available in
a hardware or serial interface and comes in quad
flat no-lead (QFN) packaging. The CSD88584/99
