The FAN73832MX is an integrated high-side and low-side gate drive IC (integrated circuit) component designed for driving MOSFETs and IGBTs in bridge-topology applications. It provides a reliable and efficient solution for various power conversion systems, such as motor drives, DC-DC converters, and UPS (uninterruptible power supply) systems. Let's delve into some of its key features:
1. Bootstrap Power Supply: The FAN73832MX utilizes a bootstrap power supply, which allows it to drive high-side MOSFETs with voltages higher than the input supply voltage. This eliminates the need for an external isolated power supply, simplifying the system design.
2. High Gate Drive Capability: This IC component can drive both the high-side and low-side gates with a maximum peak output current of 350mA. It ensures efficient switching transitions and optimal performance of power devices.
3. Under-Voltage Lockout: The FAN73832MX incorporates an under-voltage lockout (UVLO) protection feature. It monitors the DC supply voltage to prohibit operation below the specified threshold, preventing damage to the power devices during undervoltage conditions.
4. Advanced Shoot-Through Protection: To prevent shoot-through current (both high-side and low-side FETs conducting simultaneously), this component embeds advanced logic circuitry
