【產品特性】

There is zero coding required by the customer to get their motor spinning using the DRV10963.
Reduces power consumption by up to 75 percent
Flexibility to add advanced control
Cheaper manufacturing, simplicity.

The DRV10963 implements an effiecent and quite pure sinusodial sensorless BEMF three phase BLDC motor control scheme
Wide operating voltage range of 2.1 to 5.5 V for the DRV10963 and low quiescent current of 15 uA extends the battery life of portable devices.
Can be combined with an MSP430 microcontroller for designs requiring user interface and closed-loop speed control.
BOM requirement is only 20% of required space for discrete solution.

【文字介紹】

DRV10963 is a three phase, sensorless motor driver with integrated power MOSFETs with drive currentcapability up to 680 mA peak. DRV10866 is specifically designed for low noise and low external component count fan motor drive applications. DRV10963 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. DRV10963 outputs either FG or 1/2 FG to indicate motor speed with open drain output. A 150° sensorless BEMF control scheme is implemented for a three phase motor. DRV10963 is available in the thermally efficient 10-pin, 3-mm x 3-mm x 0.75-mm SON (DSC) package. The operating temperature is specified from -40°C to 125°C .
