Texas Instruments provides a recommended PCB layout in the DRV5023 datasheet, which includes guidelines for component placement, routing, and thermal management. It's essential to follow these guidelines to ensure optimal performance and minimize electromagnetic interference (EMI).
The sense resistor value depends on the desired current sensing accuracy and the maximum current that the device will handle. A smaller sense resistor value provides better accuracy but increases power consumption. Texas Instruments provides a sense resistor calculation tool to help with selection.
The DRV5023BIEDBZTQ1 has an operating temperature range of -40°C to 125°C. However, the device's performance and accuracy may degrade at extreme temperatures. It's essential to consider the operating temperature range when designing the system.
The DRV5023BIEDBZTQ1 has built-in overcurrent protection and fault detection features. The device provides an FAULT pin that indicates an overcurrent or overtemperature condition. The device can also be configured to latch off or retry after a fault event. Refer to the datasheet for more information on fault handling and configuration.
Texas Instruments recommends using a 10uF ceramic capacitor and a 1uF ceramic capacitor in parallel as close as possible to the device's power pins (VIN and VCC) to ensure stable operation and minimize noise. Additional decoupling capacitors may be required depending on the system design and layout.
