IR IRMD2336DJ三相栅极驱动参考设计

IR公司的IRS2336xD是高压高速功率MOSFET和IGBT栅极驱动器,具有三个高边和低边参考输出通路,能驱动多达6个IGBT/MOSFET功率器件,每路的栅极驱动电源高达20V(集成了升压功能),3.3V输入逻辑常兼容,并集成了死区保护,具有过流保护和超温关断输入以及交叉导通保护等. IRS2336xD典型应用包括电器马达驱动,伺服驱动,微型逆变器驱动和通用三相逆变器等.本文介绍了IRS2336xD主要特性,方框图, 典型应用框图以及IRMD2336DJ参考设计的主要特性,方框图和详细电路图和所用材料清单(BOM).

The IRS2336xD are high voltage, high speed, power MOSFET and IGBT gate drivers with three high-side and three low-side referenced output channels for 3-phase applications. This IC is designed to be used with low-cost bootstrap power supplies; the bootstrap diode functionality has been integrated into this device to reduce the component count and the PCB size. Proprietary HVIC and latch immune CMOS technologies have been implemented in a rugged monolithic structure. The floating logic input is compatible with standard CMOS or LSTTL outputs (down to 3.3 V logic). A current trip function which terminates all six outputs can be derived from an external current sense resistor. Enable functionality is available to terminate all six outputs simultaneously.

An open-drain FAULT signal is provided to indicate that a fault (e.g., over-current, over-temperature, or undervoltage shutdown event) has occurred. Fault conditions are cleared automatically after a delay programmed externally via an RC network connected to the RCIN input. The output drivers feature a high-pulse current buffer stage designed for minimum driver cross-conduction. Shoot-through protection circuitry and a minimum deadtime circuitry have been integrated into this IC. Propagation delays are matched to simplify the HVIC’s use in high frequency applications. The floating channels can be used to drive N-channel power MOSFETs or IGBTs in the high-side configuration, which operate up to 600 V.

IRMD2336DJ参考设计

The IRMD2336DJ is a reference design kit for the IRS2336DJ three phase gate driver IC with integrated bootstrap functionality. The design kit includes a complete drive system board with an input rectifier, control power supplies, digital motor control IC and power inverter. Safety features include protections against motor line-to-line and lineto- DC Bus(-) short situations. The power stage features the IRS2336DJ gate driver and six discrete IGBT power switches allowing for easy customization. The included PC based GUI software allows the user to drive an Induction Motor in open-loop Volts-per-Hertz mode of operation using the on-board digital control IC. The motor speed and system parameters such as PWM frequency and deadtime can be modified using the GUI. Alternately, the IRS2336DJ gate drive input PWM signals can be supplied externally by patching in signals through an onboard connector.

Product Summary



The IRMD2336DJ reference design kit supports the evaluation of the IRS2336DJ which is a high voltage power MOSFET and IGBT driver. The reference design is a full-function unit operating out of 220VAC input. An onboard digital controller IC enables driving an Induction Motor in open-loop Volts-per-Hertz mode. The included GUI software allows modification of system parameters in order to drive an induction motor in open-loop Volts-per- Hertz mode and study the IRS2336DJ high voltage gate driver IC by changing parameters such as PWM frequency and deadtime. The reference design is equipped with protection against motor line-to-line and line-to- DC Bus(-) short by way of the motor overcurrent protection function provided by IRS2336DJ and also a GUI software controlled motor current limit. The board includes multiple test points to facilitate monitoring IRS2336DJ input and output signal waveforms and examining its various features.
