DRV8316-Q1 Three-Phase Integrated FET Motor Driver
1 Features
3 Description
•
AEC-Q100 qualified for automotive applications
– Temperature grade 1: –40°C ≤ TA ≤ 125°C
Three-phase BLDC motor driver
4.5-V to 35-V operating voltage (40-V abs max)
High output current capability: 8-A Peak
Low MOSFET 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
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.

– 6x PWM control interface
– 3x PWM control interface
•
Supports up to 200-kHz PWM frequency for low
inductance motor support
Cycle-by-cycle current limit
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.

Integrated built-in current sense
– Doesn't require external current sense resistors
Hardware or 5-MHz 16-bit SPI interface
Supports 1.8-V, 3.3-V, and 5-V logic inputs
Built-in 3.3-V (5%), 30-mA LDO regulator
Built-in 3.3-V/5-V, 200-mA buck regulator
