The three-phase brushless motor pre-driver DRV8307 can drive brushless DC and brushless AC (BLAC) - often referred to as permanent magnet synchronous (PMSM). Aimed at 12V and 24V motors, this simple pre-driver features a PWM current control interface, three Hall sensor inputs, and locked rotor detection and restart.
The DRV8307EVM (evaluation module) serves as a user-friendly evaluation kit to demonstrate TI's brushless motor driver DRV8307. Users can control the DRV8307 with an onboard potentiometer or can supply a PWM to a dedicated test pin. The EVM is a cost-effective platform that speeds development for quicker time to market. Applications include pumps and industrial equipment, currency counters and printers.
