AMT49406GLPTR

Description

Product Details

The AMT49406 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 AMT49406 is available in a 24-contact 4 mm × 4 mm QFN 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
