BQ24380DSGT Frequently Asked Questions (FAQs)
Texas Instruments provides a recommended PCB layout in the datasheet (Figure 23) and in the application note SLUA645. It's essential to follow these guidelines to minimize noise, ensure proper thermal performance, and optimize the device's functionality.
The sense resistor value depends on the desired current sensing range and the input voltage. TI provides a sense resistor calculation tool (SLVCAT) and an application note (SLUA644) to help with the selection process. Typically, a 1-mΩ to 10-mΩ sense resistor is used for most applications.
The EN (Enable) pin is used to enable or disable the device. When EN is high, the device is enabled, and when EN is low, the device is disabled. This pin can be used to implement power-saving modes or to reset the device. It's recommended to connect EN to a logic-level input or a pull-up resistor to ensure proper operation.
The FAULT pin is an open-drain output that indicates a fault condition, such as overcurrent, overvoltage, or undervoltage. When a fault occurs, the FAULT pin is pulled low. The device will automatically recover from the fault condition when the fault is removed. It's recommended to connect the FAULT pin to a logic-level input or a pull-up resistor to ensure proper operation.
The recommended input capacitor value is 10 μF to 22 μF, with a voltage rating of 25 V or higher. A low-ESR ceramic capacitor (e.g., X5R or X7R) is recommended to minimize noise and ensure proper operation.
