IC family shrinks gate drive circuits

24 October 2001 Power Electronics / Power Management

International Rectifier's IR2180 series 600 V MOSFET and IGBT gate driver ICs are simple, small and cost effective MOSFET or IGBT gate driver solutions for applications up to 12 kW. According to IR they can save over 30% in parts count in a 50% smaller PCB area compared to a discrete-based, opto-coupler driver circuit. The IR2180 series ICs include 600 V gate drivers rated at 1,4 A pull-up and 1,8 A pull-down output source/sink current in an 8-lead SOIC or PDIP package.

Applications include uninterruptible power supply and switched mode power supply applications up to 12 kW, and AC motor drives up to 10 hp. The new driver ICs simplify circuits and are ideal for high-density, high-current designs. With the addition of few external components, the ICs provide full driver capability with fast switching speeds and low-power dissipation. They further simplify circuit designs by using a bootstrap supply while optocoupler-based circuits require an auxiliary power supply. The IR2180 series comes in six different configurations.

Delay matching between the low-side and high-side driver is within ±50 ns, allowing dead-time control down to 500 ns for better speed range and torque control in motor drive applications. The IR2181 series integrates one high-side and one low-side gate driver. They are half bridge drivers with a separate low-side inverted input and a high-side input. The IR2184 series are single-input, half-bridge drivers with a separate shutdown pin.

The devices are offered in standard 8 and 14-pin SOIC or PDIP packages.
