Product Overview

The DRV11873PWPR is a 12V 3-phase sensorless BLDC Motor Controller with integrated power MOSFETs with drive current capability up to 1.5-A continuous and 2-A peak. It is specifically designed for fan motor drive applications with low noise and low external component count. It has built-in over-current protection with no external current sense resistor needed. The synchronous rectification mode of operation achieves increased efficiency for motor driver applications. DRV11873PWPR 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 450mΩ
  • 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
  • 7 to 100kHz PWMIN Input
  • Over-current protection with adjustable limit
  • Through External Resistor
  • Lock detection
  • Voltage Surge Protection
  • UVLO
  • Thermal shutdown
  • Green product and no Sb/Br


Signal Processing, Motor Drive & Control


Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
