Description
General part information
DRV8316-Q1 Series
The DRV8316-Q1 provides a single-chip power stage solution for customers driving 12-V brushless-DC motors up to 40-W. The DRV8316-Q1 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-Q1 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-Q1 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.
There are a large number of protection features integrated into the DRV8316-Q1, intended to protect the device, motor, and system against fault events.
