A good PCB layout for the BQ24616RGER involves placing the device close to the battery, using a solid ground plane, and keeping the high-current paths short and wide. It's also recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
The selection of external components for the BQ24616RGER depends on the specific application requirements. For the inductor, consider the maximum current rating, inductance value, and DC resistance. For the capacitors, consider the voltage rating, capacitance value, and ESR. TI provides a component selection guide in the datasheet and application notes.
The BQ24616RGER is rated for operation from -40°C to 125°C. High temperatures can affect the device's performance, reducing its efficiency and increasing its power losses. It's essential to ensure proper thermal management, such as using a heat sink or a thermal pad, to maintain a safe operating temperature.
The BQ24616RGER has a built-in overcurrent protection feature. To implement it, connect the OCP pin to a resistor divider network that sets the overcurrent threshold. The recommended settings depend on the specific application requirements, but a typical value for the OCP threshold is 1.5A to 2A.
The BQ24616RGER and BQ24650 are both high-performance battery charger ICs, but they have different features and specifications. The BQ24616RGER has a higher maximum charging current (3A vs. 2A) and a wider input voltage range (5V to 24V vs. 5V to 18V). The BQ24650 has a more advanced feature set, including a built-in USB OTG detector and a VBUS discharge function.
