The DRV8316 provides a single-chip power stage solution for customers driving 12-V and 24-V brushless-DC motors . The DRV8316 integrates three 1/2-H bridges with 40-V absolute maximum capability and a very low RDS(ON) of 95mOhms (high-side plus low-side) to enable high power drive capability. Current is sensed using an integrated current sensing feature which eliminates the need for external sense resistors. Power management features of an adjustable buck regulator and LDO generate the necessary voltage rails for the device and can be used to power external circuits.
DRV8316 implements a 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 microcontroler. The DRV8316 is capable of driving a PWM frequency up to 200 kHz. The control scheme is highly configurable through hardware pins or register settings ranging from motor current limiting behavior to fault response.
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.
There are a large number of protection features integrated into the DRV8316, intended to protect the device, motor, and system against fault events.
Refer Section 9.1 for design consideration and recommendation on device usage.
