NXP MC34937 Internal Block Diagram


  • Extended supply voltage operating range: 6.0 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 5.0 V logic interface to MCUs
  • Integrated current sensing amplifier
  • Device configuration and diagnostics through the SPI
