Features

System Features

  • Extended supply voltage operating range: 6 to 58 V
  • Wide dead time range (50 ns to 12 μs) programmable via the SPI port
  • External FET gate drive capability of >1.0 A with protection
  • Charge pump ensures sufficient external FET drive at low supply voltages
  • Device protection against reverse charge-injection from CGD and CGS of external FETS
  • Integrated overcurrent, desaturation, and phase fault-detection
  • Immunity against positive or negative transient voltage spikes on the gate driver
  • Current shoot-through protection built into dead time control
  • Supports direct 3.3 V and 5 V logic interface to MCUs
  • Integrated current sensing amplifier
  • Device configuration and diagnostics through the SPI
  • Parallel, SPI interface and input control
  • Load current(IL) 1 A (Typ)
  • 6 Channels
  • Drain-to-Source on resistance 0, 5500 mOhm RDS(ON) (Typ)
