IRS2133

Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All voltage parameters are absolute voltages referenced to COM. The thermal resistance and power dissipation ratings are measured under board mounted and still air conditions. Zener clamps are included between V_CC & COM (25 V), V_CC & V_SS (20V), and V_Bx & V_Sx (20 V).

The IRS213(3, 5) are high voltage, high speed power MOSFET and IGBT drivers with three independent high and low side referenced output channels for 3-phase applications. Proprietary HVIC technology enables ruggedized monolithic construction. Logic inputs are compatible with CMOS or LSTTL outputs, down to 2.5 V logic. An independent operational amplifier provides analog feedback of bridge current via an external current sense resistor. A current trip function which terminates all six outputs can also derived from this resistor. A shutdown function is available to terminate all six outputs. An open drain FAULT signal is provided to indicate that an over-current or undervoltage shutdown has occurred. Fault conditions are cleared with the FLT-CLR lead.

The output drivers IRS2133 feature a high pulse current buffer stage designed for minimum driver cross-conduction. Propagation
delays are matched to simplify use in high frequencies applications. The floating channels can be used to drive N-channel power MOSFETs or IGBTs in the high side configuration which operates up to 600 V.
