Evaluation board for three phase brushless motors up to 80W
The TPD420xF family of three BLDC driver ICs use high voltage PWM control and are fabricated with a high voltage 500V / 600V process. They contain a level-shifting high-side driver, low-side driver, MOSFET outputs, voltage regulator and multiple circuit protections including overcurrent, undervoltage and thermal. A three-shunt resistor circuit is also included for three-phase current sensing. The TPD4204F and TPD4206F are rated at 2.5A while the TPD4207F is capable of delivering 5A of output current.
The devices are housed in a small SSOP30 package measuring just 20.0mm x 14.2mm x 2.2mm and accept logic-level inputs from a microcontroller or motor controller to drive the BLDC motor.
The evaluation board measures 100mm x 100mm and contains all of the required passive components required to create a BLDC motor driver. Multiple pads are provided to connect and configure the external driver and motor. Probing pads are also provided to facilitate easy monitoring of key voltage waveforms, thereby allowing designers to accurately monitor performance of development projects.
