3 Description
The DRV832x family of devices is an integrated gate
driver for three-phase applications. The devices
provide three half-bridge gate drivers, each capable
of driving high-side and low-side N-channel power
MOSFETs. The DRV832x generates the correct gate
drive voltages using an integrated charge pump for
the high-side MOSFETs and a linear regulator for the
low-side MOSFETs. The Smart Gate Drive
architecture supports peak gate drive currents up to
1-A source and 2-A. The DRV832x can operate from
a single power supply and supports a wide input
supply range of 6 to 60 V for the gate driver and 4 to
60 V for the optional buck regulator.
The 6x, 3x, 1x, and independent input PWM modes
allow for simple interfacing to controller circuits. The
configuration settings for the gate driver and device
are highly configurable through the SPI or hardware
(H/W) interface. The DRV8323 and DRV8323R
devices integrate three low-side current sense
amplifiers that allow bidirectional current sensing on
all three phases of the drive stage. The DRV8320R
and DRV8323R devices integrate a 600-mA buck
regulator.
A low-power sleep mode is provided to achieve low
quiescent current draw by shutting down most of the
internal circuitry. Internal protection functions are
provided for undervoltage lockout, charge pump fault,
MOSFET overcurrent, MOSFET short circuit, gate
driver fault, and overtemperature. Fault conditions are
indicated on the nFAULT pin with details through the
device registers for SPI device variants.
