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).
The BQ24272RGER can be configured for different charging profiles using the I2C interface. The device has several registers that can be programmed to set the charging voltage, current, and termination conditions. The datasheet provides a detailed description of the registers and their functions, and the application note SLUA443 provides examples of how to configure the device for different charging profiles.
The BQ24272RGER can handle input voltages up to 20V, but it is recommended to limit the input voltage to 18V to ensure reliable operation and to prevent damage to the device.
The BQ24272RGER has a built-in over-voltage protection (OVP) circuit that detects when the input voltage exceeds a certain threshold (typically 18.5V). When OVP is triggered, the device shuts down to prevent damage to the internal components and the external circuitry.
Yes, the BQ24272RGER can be used for charging multiple batteries in parallel. However, it is recommended to use a separate charger IC for each battery to ensure that each battery is charged safely and efficiently. The application note SLUA445 provides guidelines for charging multiple batteries in parallel using the BQ24272RGER.
