三相PWM电机驱动器 Three Phase PWM Motor Driver
DESCRIPON
The DRV8312/32 are high performance, integrated three phase motor drivers with an advanced
protection system. Because of the low RDSon of the power MOSFETs and intelligent gate drive design, the efficiency of these motor drivers can be up to 97%, which enables the use of smaller power supplies and heatsinks, and are good candidates for energy efficient applications.
FEATURES
• High-Efficiency Power Stage up to 97% with Low RDSon MOSFETs 80 mΩ at TJ = 25°C
• Operating Supply Voltage up to 50 V 70 V Absolute Maximum
• DRV8312 power pad down: up to 3.5 A Continuous Phase Current 6.5 A Peak
• DRV8332 power pad up: up to 8 A Continuous Phase Current 13 A Peak
• Independent Control of Three Phases
• PWM Operating Frequency up to 500 kHz
• Integrated Self-Protection Circuits Including Undervoltage, Overtemperature, Overload, and
Short Circuit
• Programmable Cycle-by-Cycle Current Limit Protection
• Independent Supply and Ground Pins for Each Half Bridge
• Intelligent Gate Drive and Cross Conduction Prevention
• No External Snubber or Schottky Diode is Required
APPLICATIONS
• BLDC Motors
• Three Phase Permanent Magnet Synchronous Motors
• Inverters
• Half Bridge Drivers
• Robotic Control Systems
