Power systems come in many different forms and each has a dedicated application field and working principle. The PMIC - Motor Drivers, Controllers segment is no exception. The PS8AES06PE is one such product, designed and manufactured by Power Integrations, offering a range of features, along with a flexible solution to traditional motor control strategies.

This motor driver is designed to drive permanent magnet synchronous (PMSM) motors up to 7kW of peak power; the IC features a 6-phase high-side MOSFET and low-side MOSFET pre-driver, offering both inrush current and over-temperature management.

The product’s high-side driver supports multiple control topologies to control the motor speed and torque. These consist of Field Oriented Control (FOC), Open Loop Control (OLC) and Peak Current Mode Control (PCMC). In addition to this, the PS8AES06PE also operates with a fast AND gate PWMB driver, featuring 10-bit PWM resolution. This is capable of achieving switching frequencies of up to 20 kHz.

The product also features a Vbs pin that allows the user to monitor the summed voltage of all power and ground phases. Furthermore, this IC is capable of optimizing inverter performance thanks to its integrated over-voltage protection and short-circuit protection mechanisms.

In terms of safety, the IC provides over-current detection and negative switching diagnosis. This ensures the product’s built-in safety is constantly monitored and optimized. Additionally, the IC includes noise filtering mechanisms such as a built-in EMI filter, slew rate control and over-current detection.

Finally, the device is also able to operate in a stand-alone mode or with an external controller. In a stand-alone mode, the device is able to use integrated logic and sense inputs to autonomously drive and control the motor. Alternatively, the device can be directly interfaced with a controller to process higher level algorithms, allowing for more accurate motor control.

Hence, the PS8AES06PE motor driver offers an effective solution to controlling permanent magnet synchronous motors. With a range of features, it offers a flexible control solution to traditional motor control strategies. Furthermore, it has a range of integrated safety features, maximizing system reliability and performance.
