The IRS2332DSPBF is a 3-phase high voltage high speed power MOSFET and IGBT Half-bridge Driver with three independent high and low-side referenced output channels. Proprietary HVIC technology enables ruggedized monolithic construction. Logic inputs are compatible with CMOS or LSTTL outputs, down to 3.3V logic. A ground-referenced operational amplifier provides analogue feedback of bridge current via an external current sense resistor. A current trip function which terminates all six outputs is also derived from this resistor. An open drain FAULT signal indicates if an over-current or under-voltage shutdown has occurred. The output drivers feature a high pulse current buffer stage designed for minimum driver cross-conduction. Propagation delays are matched to simplify use at high frequencies. The floating channel can be used to drive N-channel power MOSFET or IGBT in the high-side configuration which operates up to 600V.

• Floating channel designed for bootstrap operation
• Tolerant to negative transient voltage (dV
• dt immune)
• Under-voltage lockout for all channels
• Overcurrent shutdown turns OFF all six drivers
• Independent half-bridge drivers
• Matched propagation delay for all channels
• 3.3V Logic compatible
• Outputs out of phase with inputs
• Cross-conduction prevention logic

• Integrated operational amplifier
• Integrated bootstrap diode function
• 0.7µs Typical dead-time
