The FAN7391MX is an integrated circuit (IC) component primarily designed for use in motor control applications. It belongs to the FAN7391 series of ICs, which are known for their high-performance gate drivers.
Key features of the FAN7391MX include:
1. Gate Drive Functionality: The FAN7391MX provides dual high- and low-side gate driver channels, making it suitable for driving both high-side and low-side power MOSFETs or IGBTs. This feature allows for efficient control of motors or other high-power devices.
2. Voltage Level Shifting: It incorporates a bootstrap capacitor and diode to provide a voltage level shift for the high-side gate driver. This ensures compatibility with the low-side signal, facilitating reliable and synchronized switching of the power devices.
3. Logic Level Inputs: The IC supports direct logic level inputs to the high- and low-side gate drivers, enabling easy interfacing with microcontrollers or digital logic circuits. The logic inputs are compatible with both TTL and CMOS levels.
4. Under-Voltage Lockout (UVLO) Protection: The FAN7391MX includes UVLO protection for both the high- and low-side gate drivers. This feature ensures that the gate drivers remain inactive when the supply voltage drops below a specified threshold, safeguarding against improper device operation
