The recommended layout and placement for the BQ24195LRGET involves placing the device close to the battery, using a solid ground plane, and keeping the input and output capacitors close to the device. Additionally, the device should be placed away from high-current carrying traces and heat sources.
To optimize the charging current and voltage for your specific battery, you can use the ISET pin to adjust the charging current and the VREG pin to adjust the charging voltage. You can also use the EN pin to enable or disable the charging function.
The BQ24195LRGET has a thermal shutdown feature that turns off the device when the junction temperature exceeds 150°C. To minimize thermal issues, ensure good airflow, use a heat sink if necessary, and avoid blocking the thermal pad on the bottom of the device.
The BQ24195LRGET has built-in OVP and UVP features. For OVP, the device will turn off if the input voltage exceeds 6.5V. For UVP, the device will turn off if the input voltage falls below 3.5V. You can also use external components to customize the OVP and UVP thresholds.
To minimize EMI and EMC issues, use a shielded cable for the input and output connections, keep the device away from high-frequency sources, and use a common-mode choke or ferrite bead on the input and output lines.
