Monolithic Power Systems

100V three-phase BLDC motor pre-drivers

The MP6537/8/9 is a gate driver family designed for three-phase, brushless DC motor driver applications. It is capable of driving three half-bridges consisting of six N-channel power MOSFETs up to 100V. This driver family uses a bootstrap capacitor to generate a supply voltage for the high-side MOSFET driver. An internal charge pump maintains the high-side gate driver if the output is held high for an extended period of time. Full protection features include programmable Over-Current Protection (OCP), adjustable dead-time control, Under Voltage Lockout (UVLO), and thermal shutdown.

  • Supports 100V operation
  • Internal LDO supports external NPN for high-current drive requirements
  • Low-power sleep mode for battery-powered applications
  • Adjustable dead-time control to prevent shoot-through
  • Fault indication output
  • 120V VBST maximum voltage • Integrated current sense amplifier
  • Programmable Over-Current Protection (OCP) of external MOSFETs
  • Thermal shutdown and Under Voltage Lockout (UVLO) protection
  • TSSOP-28 and QFN-28 packages
