A good PCB layout for the DRV5023AJQDBZT 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.
The sense resistor value depends on the desired current sense accuracy and the maximum current in your application. A smaller sense resistor value provides better accuracy but increases power loss. TI provides a sense resistor calculation tool and guidelines in the datasheet and application notes.
The DRV5023AJQDBZT has an operating temperature range of -40°C to 125°C. However, the device's performance and reliability may degrade at extreme temperatures. Ensure proper thermal design and heat sinking to maintain a safe operating temperature.
Use a voltage regulator or a transient voltage suppressor (TVS) to protect the DRV5023AJQDBZT from overvoltage conditions. For undervoltage protection, use a voltage supervisor or a power-on reset (POR) circuit to ensure the device operates within its specified voltage range.
A 10uF to 22uF X5R or X7R ceramic capacitor is recommended for the input capacitor. This value provides a good balance between filtering and stability. Ensure the capacitor is rated for the input voltage and has a low equivalent series resistance (ESR).
