Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Shenzhen Mingjiada Electronics Co., Ltd. supply and recycle DRV8316CTQRGFRQ1 (TI) 8A, automotive grade three-phase FET motor drivers.

Overview:

The DRV8316CTQRGFRQ1 three-phase integrated FET Motor driver is a single-chip power-level solution designed to drive 12V brushless DC motors up to 40W. The DRV8316-Q1 driver integrates three 1/2-H Bridges with an absolute maximum voltage of 40V and an ultra-low RDS(ON) of 95mΩ (high side plus low side) for high-power drive capability.

The DRV8316-Q1 motor driver eliminates the need for external current detection resistors through integrated current detection. The power management capabilities of the adjustable step-down regulator and LDO generate the necessary voltage rail for the DRV8316-Q1 device, which can be used to power external circuits.

The DRV8316-Q1 implements a 6x or 3x PWM control scheme and can be used to implement sensorless or sensorless field oriented control (FOC), sinusoidal control, or ladder control using an external microcontroller. The DRV8316-Q1 is capable of driving PWM frequencies up to 200kHz. The control scheme is highly configurable and can be configured via hardware pin or register Settings, ranging from motor current limiting behavior to fault response.

The DRV8316-Q1 integrates multiple protection features designed to protect the device, motor and system in the event of a failure. The device complies with the AEC-Q100 standard for automotive applications.
