BQ24161BRGER datasheet by Texas Instruments

BQ24161BRGER Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the BQ24161BRGER?
  Texas Instruments provides a recommended layout and placement guide in the application note SLUA444, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize electromagnetic interference (EMI).
• How do I configure the BQ24161BRGER for different charging scenarios?
  The BQ24161BRGER has several configuration options for different charging scenarios, such as USB-OTG, USB-BC, and proprietary charging. The device can be configured using external resistors on the I2C interface or through software control using the I2C interface. Refer to the application note SLUA443 for more information.
• What is the maximum current rating for the BQ24161BRGER?
  The BQ24161BRGER has a maximum current rating of 2.5A, but this can be limited by the external components, such as the FETs and inductors, used in the design. It's essential to ensure that the external components are rated for the desired maximum current to prevent overheating and damage.
• How does the BQ24161BRGER handle over-voltage protection (OVP) and over-current protection (OCP)?
  The BQ24161BRGER has built-in OVP and OCP features that can be configured using external resistors or through software control. The device can detect over-voltage conditions and limit the input current to prevent damage. It also has a programmable OCP threshold to prevent excessive current draw.
• Can the BQ24161BRGER be used in a battery-only configuration?
  Yes, the BQ24161BRGER can be used in a battery-only configuration, but it requires an external power path controller to manage the battery charging and discharging. The device can be configured to operate in a battery-only mode using the I2C interface or external resistors.
