- Полное описание
The A4931METTR-T is a 3-phase brushless DC Motor Pre-Driver with overvoltage protection and thermal shutdown circuitry. The driver is capable of driving a wide range of N-channel power MOSFETs and can support motor supply voltages up to 30V. Commutation logic is determined by three Hall-element inputs spaced at 120°. It features fixed off-time pulse width modulation (PWM) current control for limiting inrush current, locked-rotor protection with adjustable delay, thermal shutdown, overvoltage monitor and synchronous rectification. It offers enable, direction and brake inputs that can control current using either phase or enable chopping. Logic outputs FG1 and FG2 can be used to accurately measure motor rotation.
• Synchronous rectification for low power dissipation
• PWM current limiting
• Dead time protection
• Standby mode
• Lock detect protection
