Three-phase inverter driver IC for motor drives
20 November 2002
Power Electronics / Power Management
International Rectifier's IR2136 family of three-phase inverter-driver ICs for variable speed motor drives integrate six MOSFET or IGBT high voltage gate drivers with a range of protection functions at 30% lower system cost than opto-coupler solutions. They can also simplify design with as much as 30% lower component count and shrink gate drive circuit size by up to 50% compared to alternative solutions. The IR2136 IC family targets energy-efficient, electronically-driven variable speed electric motors for home appliances, or light industrial and automotive motor drives. The 600 V IR2136 ICs are CMOS- or LSTTL-output compatible, down to 3,3 V logic for direct interface with a microcontroller or other logic devices and offer 120 mA/250 mA output source/sink current. They enable rugged designs with up to 50 V/ns dV/dt immunity and low di/dt drive current for noise immunity, and allow high frequency operation with a deadtime as low as 250 ns, and typical turn-on/turn-off time of 400 ns. The output drivers feature a high pulse current buffer stage designed for minimum driver cross-conduction. Matched propagation delays for all six channels in the single IC package ensure consistent high frequency operation. High frequency provides better motor torque performance at low speed and reduces audible noise.
