SBVS206A – NOVEMBER 2012 – REVISED MARCH 2015 DRV10866 5-V, 3-Phase, Sensorless BLDC Motor Driver
1 Features 3 Description DRV10866 is a 3-phase, sensorless motor driver
with integrated power MOSFETs with drive current
capability up to 680-mA peak. DRV10866 is
specifically designed for low noise and low external
component count fan motor drive applications.
DRV10866 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.
DRV10866 outputs either FG or ВЅ FG to indicate
motor speed with open-drain output. A 150В°
sensorless BEMF control scheme is implemented for
a 3-phase motor. DRV10866 is available in the
thermally efficient 10-pin, 3-mm Г— 3-mm Г— 0.75-mm
SON (DSC) package. The operating temperature is
specified from –40В°C to 125В°C. 1 Input Voltage Range: 1.65 V to 5.5 V …
