Introduction

The LM5111-2M is an all-in-one gate drive IC from Texas Instruments, part of their advanced power management integrated circuit (PMIC) family. It is perfect for applications including motor and motor control, power supply, and power system control. The LM5111-2M is most often seen in motors and motor drives because of its unique combination of features that allow it to provide both power to the motor coils as well as handle the logic signals from the microcontroller.

Features

The LM5111-2M features a high-isolation voltage of up to 20 volts, which is perfect for motors and motor control. It also offers adjustable PWM frequency, integrated ESD protection, and configurable source-currents down to the milliamp level. Additionally, the device has an integrated free-wheeling diode, allowing it to handle a high amount of load current while keeping the power consumption of the device to a minimum. Other features of the LM5111-2M include temperature monitoring and protection, voltage monitoring, and over-current protection.

Application Field

The LM5111-2M is a great choice for any motor or motor control application. Its combination of features makes it well-suited for controlling both large and small motors, and for providing power to the motors’ coils. The device can also be used in power supply applications, as it allows for a high amount of current to be drawn from the power source and provides isolation between the power supply and the logic signals. Additionally, the LM5111-2M can be used in power systems, such as in renewable energy systems and DC-DC converters.

Working Principle

The LM5111-2M works by converting input logic signals into two separate outputs (A and B) that are passed to the motor coils. These outputs can be configured as either Pulse Width Modulated (PWM) signals or as digital signals. In PWM mode, the LM5111-2M will pulse the outputs at a given frequency, allowing for precise control of the motor’s speed and torque. The frequency of the outputs can be adjusted using a number of parameters, such as the duty cycle, voltage, and current levels. In digital mode, the LM5111-2M will generate a digital output, which can be used for controlling the speed and direction of a motor, as well as other applications like LED dimming. The device also offers temperature monitoring and protection, voltage monitoring, over-current protection, and adjustable source-currents down to the milliamp level.

Conclusion

The LM5111-2M is a powerful and versatile gate drive IC from Texas Instruments that is perfect for a wide range of motor and motor control applications. Its high isolation voltage, adjustable PWM frequency, integrated free-wheeling diode, and configurable source-currents make it an ideal choice for medium- to low-power applications. Additionally, the device provides temperature monitoring and protection, voltage monitoring, and over-current protection, all in a single package.
