3 Description
The DRV835xF family of devices are highly-integrated
gate drivers for three-phase brushless DC (BLDC)
motor applications. The device variants provide
optional integrated current shunt amplifiers to support
different motor control schemes.
The DRV835xF uses smart gate drive (SGD)
architecture to decrease the number of external
components that are typically necessary for MOSFET
slew rate control and protection circuits. The
SGD architecture also optimizes dead time to
prevent shoot-through conditions, provides flexibility
in decreasing electromagnetic interference (EMI) by
MOSFET slew rate control, and protects against gate
short circuit conditions through VGS monitors. A strong
gate pulldown circuit helps prevent unwanted dV/dt
parasitic gate turn on events
Various PWM control modes (6x, 3x, 1x, and
independent) are supported for simple interfacing to
the external controller. These modes can decrease
the number of outputs required of the controller for
the motor driver PWM control signals. This family
of devices also includes 1x PWM mode for simple
sensored trapezoidal control of a BLDC motor by
using an internal block commutation table.
