概要

This design uses a single-chip sensorless 3-phase brushless DC motor (BLDC) for driving fans quietly and smoothly. The 180 degree sinusoidal commutation sensorless algorithium is embedded inside of DRV10963, thus eliminating the need of software and firmware. DRV10963 is ideal for battery operated personal electronics & medical equipment due to low quiescent currents and low acoustics noise performance.

特長

• Low quiescent current (15uA in sleep mode) ideal for DC battery operation
• Low acoustic noise is ideal for personal electronics and medical equipment
• Sensorless 180 deg sine motor control enabling 2dB noise reduction compared to alternative solutions
• User configurable, spin-up profile to easily operate different motors
• 3-cm diameter PCB design mates with small footprint fan enclosure
• No firmware or software needed
