ON Semiconductor FAN7385MX Half-Bridge Gate Driver

The FAN7385MX from ON Semiconductor is a high-performance, high-voltage half-bridge gate driver IC designed to drive N-channel power MOSFETs and IGBTs. This gate driver is ideal for a wide range of applications, including motor controllers, DC-DC converters, and switch mode power supplies. Its robust design and advanced features ensure efficient operation and reliable performance in demanding environments.

Key Features:

• High Voltage Capability: The FAN7385MX can handle up to 600V, making it suitable for high-voltage applications. This allows for direct driving of the gates of high-voltage power MOSFETs and IGBTs.
• High Sink and Source Current: With peak source and sink currents of ±250 mA / ±500 mA, the device can rapidly charge and discharge the gate capacitance of power switches, ensuring fast switching times and reduced switching losses.
• Bootstrap Operation: The integrated high-side gate driver is designed to work with a bootstrap circuit, enabling the driving of the high-side switch in a half-bridge configuration.
• Under-Voltage Lockout (UVLO): Both the high-side and low-side drivers have UVLO protection, ensuring that the gate driver operates only when there is sufficient voltage, thus protecting the power switches from insufficient gate voltage.
• Input Logic: The FAN7385MX accepts standard CMOS or LSTTL outputs, making it compatible with a variety of control circuits.
• Interlocking Function: This feature prevents both the high-side and low-side MOSFETs or IGBTs from being on at the same time, eliminating the risk of shoot-through.
• Matched Propagation Delays: The device offers matched propagation delays for the high-side and low-side drivers, which helps in maintaining the integrity of the switching action and reducing dead-time related losses.
