A89301
A89301
50 V Ultra Low Noise FOC Motor Controller
FEATURES AND BENEFITS
• Code-free sensorless field-oriented control (FOC)
• I2C interface for speed control and status readback
• Ultra-quiet low speed operation
• Proprietary non-reverse fast startup
• Soft-On Soft-Off (SOSO) for quiet operation
• Analog / PWM / Clock mode speed control
• Closed-loop speed control
• Configurable current limit
• Windmill startup operation
• Lock detection
• Short-circuit protection (OCP)
• Brake and direction inputs
• Adjustable gate drive
APPLICATIONS
• Ceiling fans
• Pedestal fans
• Bathroom exhaust fans
• Home appliance fans and pumps
DESCRIPTION
The A89301 is a 3-phase, sensorless, brushless DC (BLDC)
motor driver (gate driver) which can operate from 5.5 to 50 V.
A field-oriented control (FOC) algorithm is fully integrated to
achieve the best efficiency and acoustic noise performance.The
device optimizes the motor startup performance in a stationary
condition, a windmill condition, and even in a reverse windmill
condition.
Motor speed is controlled through analog, PWM, or CLOCK
input. Closed-loop speed control is optional, and RPM-to-clock
frequency ratio is programmable.
A simple I2C interface is provided for setting motor-rated
voltage, rated current, rated speed, resistance, and startup
profiles. The I2C interface is also used for on/off control, speed
control, and speed readback.
The A89301 is available in a 24-contact 4 mm × 4 mm QFN
with exposed thermal pad (suffix ES). The package is lead (Pb)
free, with 100% matte-tin leadframe plating.
