Infineon PSB21553EV4 Evaluation Board: Features and Application Design
The Infineon PSB21553EV4 evaluation board serves as a comprehensive development platform for engineers to prototype and evaluate the capabilities of the TLE987x series of embedded power devices. This board is specifically designed to streamline the design process for a wide range of automotive and industrial applications, particularly those involving brushless DC (BLDC) motor control.
Key Features of the Evaluation Board
At the heart of the PSB21553EV4 is the TLE9879QXA40, a highly integrated 32-bit ARM® Cortex®-M3 microcontroller. This system-on-chip (SoC) combines the processing core with critical power components, significantly reducing the system's footprint and complexity. The board's standout features include:
Integrated MOSFET Driver: The embedded NFET driver can deliver up to 500mA source and sink current, capable of directly driving small motors or external gate drivers for higher-power stages.
On-Board Voltage Regulators: It features a linear voltage regulator (LDO) and a switch-mode power supply (SMPS), providing flexible and efficient power management for the microcontroller and peripherals.
Communication Interfaces: The board supports multiple communication protocols, including LIN transceiver for robust automotive network communication, CAN FD, and a debug interface via a dedicated connector.
Comprehensive Sensing: It integrates a current sensing amplifier and provides access to the microcontroller's ADC channels, enabling precise monitoring of motor phase currents and other critical parameters for implementing advanced sensorless Field-Oriented Control (FOC) algorithms.
User-Friendly Design: The board comes with a pre-programmed demo code, buttons for user input, and LEDs for status indication, allowing for out-of-the-box evaluation.
Application Design and Use Cases
The primary purpose of this evaluation kit is to accelerate the development of high-performance BLDC motor control systems. Its design is optimal for applications requiring compact size, high efficiency, and reliability.
1. Automotive Applications: It is exceptionally well-suited for a multitude of automotive subsystems, such as electric water pumps, oil pumps, radiator cooling fans, window lift motors, and sunroof controllers. The integrated LIN transceiver makes it ideal for nodes in a LIN network.
2. Industrial and Consumer Applications: Beyond automotive, it can be used in industrial automation (e.g., small conveyor belts, fans), home appliances (e.g., washing pumps, drones, HVAC blowers), and any device utilizing a 3-phase BLDC motor.
In a typical application design, the PSB21553EV4 board acts as the central controller. Engineers can use it to develop and fine-tune control algorithms, leveraging its on-chip features for sensorless or sensor-based control. The board can either drive low-power motors directly or its driver outputs can be connected to external power stages to control larger, more powerful motors. The provided evaluation software and ecosystem of tools, including the DAVE™ IDE, significantly reduce firmware development time.
The Infineon PSB21553EV4 evaluation board is an indispensable tool for engineers, offering a feature-rich and highly integrated platform to rapidly prototype and deploy efficient BLDC motor control solutions for the automotive and industrial markets.
