Beschreibung
Low voltage brushed DC drives are used in many applications. TI offers a rich family of brushed DC motor driver solutions with flexible control interface options for one or more brushed DC motors up to 60V. For applications which require higher torque and power, often voltages above 60VDC are used. The TIDA-00365 protected full-bridge operates at nominal 75VDC input and 10A output current and features bipolar high-side current sensing leveraging a 100V full-bridge gate driver SM72295 with integrated amplifiers and four 100V NexFET power MOSFETs with ultra-low gate charge and small SON5x6 package with low thermal resistance. The power stage is protected against over-temperature, over-current and short-circuit between the motor terminals and motor terminals to ground. Onboard power supplies provide a 12V and a 3.3V rail for the gate driver and signal chain. The host processor interface is 3.3V I/O to connect a host MCU like C2000 Piccolo MCU for brushed DC motor current control.
