PMIC - Motor Drivers, Controllers, is the area of programming and developing for motor driver controllers integrated circuit (ICs), which are often used in applications such as automotive, industrial, home appliance, medical and consumer electronics. NCV33035DWR2 is a highly integrated motor driver controller, developed by ON Semiconductor, which stands out among all the other integrated circuit devices, due to its extensive and improved performance.

NCV33035DWR2 is a high-efficiency regular 6-phase motor driver controller that is perfect for use with brushed DC and brushless DC (BLDC) motors. It has all the necessary functionalities packed into a small, thermally efficient package and has the capability to switch up to 30A per channel when working with N-channel MOSTM power Mosfets. It suits for all kinds of applications, such as blowers, pumps, purifiers, fans, and other home appliances, which it is fast and reliable.

From a functional perspective, this motor driver controller integrated circuit employs an isolated supply voltage to power, a free-running oscillator for commutation, adaptive shoot-through protection, tachometer feedback, automatic spin-up & lock, overcurrent protection, and undervoltage lockout (UVLO) protection on a single chip. Therefore, it is extremely suitable for different motor applications and satisfied with any requirement.

The working principle of NCV33035DWR2 is quite simple. It uses an on-chip power-on reset to ensure proper start-up sequence. When the power is applied, the oscillator will start to switch connected N-channel MOSFETs and drive the motors. A tachometer feedback signal is used to update the Timer and Phase Generator block, to adjust the ideal commutation timing according to the motor speed. Apart from that, the UVLO feature monitors the battery voltage and this will be turned off automatically when the voltage is below a certain value. Similarly, overcurrent protection and shoot-through protection will be triggered when the motor stall’s or the phase current exceeds the Safe Operating Area.

In conclusion, NCV33035DWR2 is an impressive motor driver controller that exhibits exceptional performance and features. It is ideal for use in high-efficiency, high-temperature applications, such as ceiling fans, pumps, compressors, and other motor-driven appliances. Its features such as Under-Voltage Lockout, Adaptive Shoot-Through Protection, Tachometer Feedback, Automatic Spin-up & Lock-up, makes it ideal for a wide range of motor control applications.
