This application note focuses on the features, application field and the working principle of MD1712FG-G.FeaturesMD1712FG-G is a motor driver IC with variable speed control and PWM frequency output. The main features of this IC are as follows.* Output stage drive: bipolar IGBT with source protection* PWM frequency: 2.5kHz – 40kHz* Output current capability: 1A – 7A* Motor operating voltage range: 5V – 24V* Logic input voltage range: 3V – 5.5V* Low on-resistance: 0.14Ω (typical)* ESD protection: 7kV(human body model)* Operating temperature range: -40°C to +125°CApplication FieldMD1712FG-G is suitable for any motor control application where speed and current control are required, such as Cooling Fans, Automotive Fans, Brushless Motors, Pump Motors, Tape Drives and Sensors. This motor driver IC can be used to drive a single brushless DC motor and is capable of providing a wide range of motor operating conditions.Working PrincipleMD1712FG-G is based on a variable speed control PWM driver IC. This driver IC includes a control input stage and two motor outputs. The motor outputs are used to control the speed and direction of the motor, while the control input stage is used to provide the PWM frequency and duty cycle of the motor driver.The PWM signal is generated by a dedicated circuit which uses the control signal from the user and the power supply voltage to generate the appropriate PWM signal. This signal is then used to control the speed and direction of the motor.The motor outputs are bipolar IGBTs with source protection. This allows the user to control the voltage, current and polarity of the motor. The maximum output current is 7A and the power supply voltage range is 5V – 24V. The switching frequency of the PWM driver is adjustable from 2.5kHz to 40kHz and the on-resistance of the driver IC is 0.14Ω (typical).ConclusionMD1712FG-G is a versatile motor driver IC which can be used to drive a single brushless DC motor.
