Product Overview

The DRV11873PWPR is a 3-phase sensorless BLDC Motor Controller with integrated power MOSFETs with drive current capability up to 1.5A continuous and 2A peak. It is specifically designed for fan motor drive applications with low noise and low external component count. It has built-in overcurrent protection with no external current sense resistor needed. The synchronous rectification mode of operation achieves increased efficiency for motor driver applications. DRV11873 outputs FG and RD to indicate motor status with open-drain output. A 150° sensorless BEMF control scheme is implemented for a three-phase motor.
  • Six integrated MOSFETs with 1.5A continuous output current
  • Total driver H + L RDSON of 450mR
  • Sensorless proprietary BMEF control scheme
  • 150° Commutation
  • Synchronous rectification PWM operation
  • FG and RD open-drain output
  • 5V LDO for external use up to 20mA
  • PWMIN Input from 7 to 100kHz
  • Overcurrent protection with adjustable limit
  • Through external resistor
  • Lock detection
  • Voltage surge protection
  • Thermal shutdown
  • Green product and no Sb/Br
