DESCRIPTION
TheAMT49406 isa 3-phase, sensorless, brushless DC(BLDC)motor driver (gate driver) which can operate from5.5 to 50V.A field-oriented control (FOC) algorithm is fully integrated to achieve the bestefficiency 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-loopspeedcontrol is optional, andRPM-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 AMT49406 is available in a 24-contact4 mm x 4 mmQFN with exposed thermal pad (suffix ES) and a 24-lead TSSOP with exposed thermal pad (suffix LP). These packages are lead (Pb) free, with 100% matte-tin leadframe plating.
