FAN7390MX Application Field and Working Principle
PMIC - Gate DriversThe FAN7390MX is an integrated circuit (IC) developed by Fanstel, a professional analog IC manufacturer. It is designed as a monolithic full-bridge gate driver with PMIC (Power Management IC) capabilities. It is ideally suited to drive a wide range of motor types and is particularly suitable for high-speed motor applications. It has several features that make it an ideal choice for motor control applications.First, the FAN7390MX is designed to provide optimal drive performance even in high-speed motor applications. It has a maximum switching frequency of 200 kHz and provides a high switching current of up to 5A. This allows the FAN7390MX to provide a fast response and rapid switching of the motor. It also helps reduce the overall power consumption of the motor, as it eliminates the need for high-speed switching of the motor.Second, the FAN7390MX is designed to ensure a soft start for the motor. This helps reduce vibration and improve the overall efficiency of the motor. It has a built-in under voltage lockout (UVLO) circuit which prevents the motor from being driven at an excessive speed during start up. It also features overvoltage protection (OVP) to detect when the voltage input is too high, and shut off the motor to prevent over-voltage damage.Third, the FAN7390MX is designed with a slew-rate control system to ensure smooth acceleration of the motor. This helps improve the control performance of the motor and also helps reduce power consumption as the motor is able to start and stop quickly without wasting energy. Additionally, it provides an adjustable dead-time compensation to improve signal accuracy and reduce electrical noise generated by the motor.Fourth, the FAN7390MX is designed to provide protection against surges and transients. It has built-in transient voltage suppressors (TVS) to protect the motor from the effects of overvoltage and excessive current. It also has open drain outputs that can be used to interface with other devices.Finally, the FAN7390MX features various protection features such as over current protection (OCP), thermal protection (TP), and current limiting (CL). In addition, it provides short circuit protection (SCP) as well as reverse polarity protection (RPP). These features help to protect the IC from damage and reduce the risk of accidents due to improper use.In summary, the FAN7390MX is an ideal choice for high-speed motor control applications. It provides optimal drive performance and provides protection against surges and transients. Its slew-rate control system helps reduce power consumption and can be used to provide quick acceleration and deceleration. Its protection features help to protect the IC and reduce the risk of accidents due to improper use.
