3 Description
DRV8316C integrates three H-bridges with 40-V
absolute maximum capability and a very low RDS(ON)
of 95 mΩ (high-side + low-side) to enable high power
drive capability for 12-V/24-V brushless-DC motors.
DRV8316C provides integrated current sensing which
eliminates the need for external sense resistors.
DRV8316C integrates power management circuits
including an voltage-adjustable buck regulator (3.3 V /
5 V, 200-mA) and LDO (3.3 V / 30 mA) that can be
used to power external circuits.
DRV8316C provides a configurable 6x or 3x PWM
control scheme which can be used to implement
sensored or sensorless field-oriented control (FOC),
sinusoidal control, or trapezoid control using an
external microcontroller. DRV8316C is capable of
driving a PWM frequency of up to 200 kHz.
DRV8316C is highly configurable either through SPI
(DRV8316CR) or pins (DRV8316CT) - PWM mode.
slew rate, OCP level, current sense gain are some of
the configurable features.
A number of protection features including supply
undervoltage lockout (UVLO), overvoltage protection
(OVP), charge pump undervoltage (CPUV),
overcurrent protection (OCP), over-temperature
warning (OTW) and over-temperature shutdown
(OTSD) are integrated into DRV8316C to protect the
device, motor, and system against fault events. Fault
conditions are indicated by the nFAULT pin.
