The CM5160 is an integrated circuit designed for the purpose of controlling motor speed in a variety of applications. It is a highly integrated, 4-channel, full-bridge microcontroller-controlled pulse-width modulated (PWM) motor control IC, with integrated MOSFETs, high-side current sensing and over-temperature protection. It is designed to provide improved motor control in comparison to more standard solutions, as well as improved fault signalling.

The application field for the CM5160 include high power brush DC motor control, stepper motor control and other high power applications involving some type of motor control. It can also be used for smaller applications such as fan control and control of small DC motors. Its feature of fault threat signalling makes it suitable for critical motor control applications such as those found in medical equipment and aerospace systems.

The working principle of the CM5160 is based on the pulse-width modulation (PWM) technology. It is a method of controlling the motor speed by varying the amount of power being supplied to the motor via a series of pulses. The duration of each pulse determines the power and speed of the motor. In the CM5160, this process is managed by the microcontroller. The advantage of this approach is that the motor has accurate steady-state control and is capable of producing smooth running at all speed.

Integrated into the CM5160 are the separate high and low-side drivers along with the high side and low side MOSFETs. These provide over-current protection as well as providing an effective and efficient way to control and manage the power to the motor. The integrated MOSFETs and drivers also reduce the size and cost of the system and make it more reliable through increased components integration.

In addition to the MOSFETs and drivers, the CM5160 also integrates current sensing. This allows for the system to accurately measure the current being supplied to the motor and allows for improved motor control by the microcontroller. The current sensing also allows for better overcurrent protection as any fault current can be sensed and reported to the user quickly.

The CM5160 also includes integrated temperature protection. This ensures that the IC remains within operational limits, as the IC will shut down if the temperature exceeds the maximum operational rating. This is extremely useful in motor control applications where the amount of heat generated due to current flow can disrupt operation of the IC.

The CM5160 is an integrated motor control solution that offers improved performance, is smaller in size and is more cost effective in comparison to more standard solutions. It is designed for motor control applications where accurate and reliable control is required, such as those found in medical equipment and aerospace systems.
