The FOD5700 is a high-performance, galvanically isolated gate driver optocoupler. It's designed to drive IGBTs and MOSFETs used in power inverter applications. The device utilizes Fairchild's coplanar packaging technology, offering excellent insulation and high common mode transient immunity (CMTI).

Applications:

• Industrial inverters
• AC and brushless DC motor drives
• Uninterruptible power supplies (UPS)
• Welding equipment
• Induction heating

Features:

• High noise immunity characterized by common mode transient immunity (CMTI) of 15 kV/μs minimum at VCM = 1500 V
• High speed: 100 ns maximum propagation delay over temperature range
• Under Voltage Lock-Out protection (UVLO) with hysteresis
• Wide operating voltage range: 10 V to 30 V
• High output current: 2.5 A peak
• Operating temperature range: -40°C to +100°C
• Safety and regulatory approvals: UL1577, IEC60747-5-5

Benefits:

• Improved system performance due to faster switching speeds, resulting in lower power losses and increased efficiency.
• Enhanced system reliability because of the high CMTI, preventing spurious triggering from noise.
• Simplified design with the integrated UVLO feature, preventing IGBT or MOSFET damage from low supply voltage.
• Robust operation in harsh environments due to the wide operating temperature range.
• Galvanic isolation provides electrical isolation between the control circuitry and the power stage, enhancing safety.

Additional Details:

The FOD5700 uses an AlGaAs LED as the input light source, which is optically coupled to an integrated circuit with a power output stage. The device requires a bypass capacitor connected between pins VCC and GND for proper operation. The recommended value is typically between 0.1 μF and 1 μF. It is available in a DIP8 package and is RoHS compliant. The device's safety approvals ensure compliance with international safety standards.
