FOD3180 – 2 A peak output current MOSFET/IGBT gate driver

The FOD3180 is a high-speed optocoupler from onsemi, designed specifically as a 2 A peak output current MOSFET/IGBT gate driver for isolated power applications.​

Key Specifications

It operates over 10-20 V VCC with -40°C to +100°C temperature range, offers 5000 Vrms isolation (7 mm creepage/clearance), 200 ns max propagation delay, 250 kHz switching, and 30 ns typical pulse width distortion. Input uses AlGaAs LED (Vf 1.43 V at 10 mA, If max 25 mA), output provides push-pull CMOS with UVLO protection and RDS(on) 1.5 Ω typical.​

Pinout and Package

Available in 8-pin DIP or SMD, pins include: 1/2 Anode/Cathode (LED input), 3 NC, 4 VE (input ground), 5 GND (output), 6/7 Output, 8 VCC. Total power dissipation is 295 mW, suited for driving MOSFETs in your power electronics like inverters or motor drives.​

Applications

Ideal for high-frequency SMPS, motor control inverters, DC-DC converters, and plasma displays, providing galvanic isolation between low-voltage control and high-voltage power stages.
