The L6386E is an integrated motor drive IC from STMicroelectronics that can be used to efficiently drive permanent magnet and brushless motors with greater power density. It features high-current outputs, allowing for a variety of motor control applications.

The L6386E is a highly integrated device that features two half-bridge channels for three-phase drives; a speed control solution with Sinusoidal Back EMF Controlled Motor Drive (SBCMD) and a failsafe brake system.

The L6386E is a highly efficient gate driver, featuring an internal 3A (5A peak) current source that continuously drives the external MOSFET gates and a wide working voltage of 3.3 to 52 volts. It also offers an external overcurrent protection system and a full suite of protection features, including under-voltage, over-voltage and over-temperature.

The device can be used to drive stepper motors, BLDC motors or DC brushed motors with a wide range of speed and current control. Its high-power output ensures that the motor can achieve high torque output at low speed, which makes it ideal for demanding motor control applications.

The L6386E features two individual High-Swing Half-Bridge Drivers (HBDs) with two independent high-current PWM outputs for controlling three-phase motors. It also features two Multi-Channel PWM Controllers that provide individually programmable speed and current limits with pre-programmed speed and acceleration profiles.

The L6386E also features a Sinusoidal Back EMF Controlled Motor Drive (SBCMD) for more efficient motor control. This feature allows for accurate speed and current control by using a continuous sinusoidal back electromotive force (EMF) to adjust the current drive to the motor. It also allows the motor to reach its desired speed more quickly and efficiently.

In addition, the L6386E includes a failsafe brake system, which provides a robust protection system. This feature is used to park the motor by abruptly shutting down the current to the motor when the external power supply is removed. This feature also provides a failsafe safety mechanism to protect against unexpected power outages or sudden over-currents.

The L6386E can be used in a variety of motor control applications, such as electric power steering (EPS) systems, robotics, electric vehicle (EV) and hybrid electric vehicle (HEV) motor drives, and motor control applications in industrial and home appliances.

The L6386E can operate in both continuous and pulsed mode of operation, making it highly versatile and easy to use. It is highly efficient, offering a maximum frequency of 8MHz and working frequencies up to 2MHz and a wide range of pulse width modulation (PWM) output voltage.

In conclusion, the L6386E is an integrated motor drive IC from STMicroelectronics that is designed for high-power motor control applications. It features two isolated high-current half-bridges, a speed control solution with Sinusoidal Back EMF Controlled Motor Drive (SBCMD) and a failsafe brake system. It can be used for a variety of applications, from electric power steering systems to electric vehicle and hybrid electric vehicle motor drives.
