To comply with energy efficiency standards worldwide designers of industrial applications such as solar inverters, uninterruptible power supplies (UPS) and motor drives require gate driver optocouplers with low power consumption and fast switching speeds.
Fairchild Semiconductor’s new FOD3184 is a 3A output current, high speed MOSFET/IGBT gate driver optocoupler consisting of an aluminum gallium arsenide (AlGaAs) light emitting diode optically coupled to a CMOS detector with PMOS and NMOS output power transistors integrated into the circuit power stage. It is suitable for high frequency driving of power MOSFETS/IGBTs used in Plasma Display Panels (PDPs), motor control inverter applications and high performance DC/DC converters,
According to Fairchild the FOD3184 offers nearly 50% reduction in propagation delay times and 13% lower power consumption compared to its FOD3120 gate driver. The device also offers high noise immunity, characterized by a minimum 35kV/µs common mode rejection (CMR) –for noisy industrial applications.
The device is packaged in an 8-pin dual in-line housing compatible with 260°C reflow processes for lead free solder compliance. Samples are available now.
