Three-Phase Gate Driver Features Extra Channel For PFC

The IRS26302D, 600V three-phase gate driver with ground-fault protection, includes a seventh drive channel for a power factor correction (PFC) switch or inverter brake. It integrates power MOSFET/IGBT gate drivers with three high-side and three low-side referenced output channels to provide 200 mA and 350 mA drive currents at up to 20V MOS gate drive capability while operating up to 600V. Other features include Vs immunity circuitry to protect the system from catastrophic events during high-current switching and short-circuit conditions, an advanced input filter, integrated bootstrap functionality, an over-current and over-temperature detection input, under-voltage lockout protection, dead-time protection, shoot-through protection, a shutdown input, fault-reporting, and compatibility with 3.3V input logic. Available in a 44-pin PLCC, price is $2.44 each/100,000. INTERNATIONAL RECTIFIER, El Segundo, CA. (310) 252-7726.
