Three-phase PWM motor driver
– 3-Phase Brushless-DC motors
4.5-V to 35-V operating voltage
– 40-V Absolute maximum voltage
High output current capability
– 8-A Peak current drive
Low on-state resistance
– 95-mΩ RDS(ON) (HS + LS) at TA = 25°C
Low power sleep mode
– 1.5-µA at VVM = 24-V, TA = 25°C
Multiple control interface options
– 6x PWM control interface
The DRV8316 provides three half-H-bridge integrated
MOSFET drivers for driving a three-phase Brushless-
DC (BLDC) motor for 12-V/24-V DC rails or battery
powered applications. These applications include
field-oriented control (FOC), sinusoidal current
control, and trapezoidal current control of BLDC
motors. The device integrates three current-sense
amplifiers (CSA) with built-in current sense for
sensing the three phase currents of BLDC motors.
Each output driver channel consists of N-channel
power MOSFETs configured in
a
half-bridge
configuration. Various PWM control modes are
supported for simple interfacing to control circuits that
can be powered by the 30-mA, 3.3-V internal
regulator (AVDD). The DRV8316R/T also supports a
buck regulator which in conjunction can support 200-
mA with programmable regulated supply. The device
supports 200-kHz maximum PWM frequency.
