A good PCB layout for the DRV5023AJQDBZRQ1 involves keeping the high-current paths short and wide, using a solid ground plane, and placing the decoupling capacitors close to the device. TI provides a recommended PCB layout in the datasheet and application notes.
When selecting an inductor for the DRV5023AJQDBZRQ1, consider the inductor's saturation current, DC resistance, and core material. A good starting point is to use an inductor with a saturation current rating of at least 1.5 times the maximum output current, and a DC resistance of less than 100 mΩ.
The DRV5023AJQDBZRQ1 is rated for operation up to 125°C ambient temperature, but the maximum junction temperature is 150°C. Ensure proper thermal design and heat sinking to maintain a safe operating temperature.
The DRV5023AJQDBZRQ1 has a built-in overcurrent protection feature. To implement it, connect a sense resistor in series with the output, and use the OCP pin to monitor the current. Set the OCP threshold by connecting a resistor divider network to the OCP pin.
Yes, the DRV5023AJQDBZRQ1 is suitable for high-reliability applications. It is built with a robust design, and TI provides a detailed reliability report and qualification data to support its use in demanding environments.
