Infineon – AUIRS20302S: Solutions for Battery-Powered Motor Control Applications

Infineon_Logo
Infineon offers a variety of driver IC and MOSFET technologies that simplify design and increase efficiency in battery-powered circuits, half bridge and full bridge topologies and motor drive applications. Robust and highly integrated 3-phase gate driver ICs minimize component count and enhance reliability, while the StrongIRFET™ power MOSFETs with their ultra low on-state resistance and high current capability offer improved performance in low frequency applications.

The AUIRS20302S is capable of driving 6 N-channel power MOSFETs using a bootstrap technique to supply the high side driving circuitry and also features embedded dead time and cross-conduction prevention functions and under-voltage and overcurrent protection with diagnostics.

FEATURES

  • 3-phase gate driver for 24V and higher drives
  • Under-voltage lockout for all channels
  • Cross-conduction prevention logic
  • Matched propagation delay for all channels
  • High negative transients immunity
