- 16S support with pin compatibility (vs BQ79614PAPRQ1)
Design Notes
For the HTQFP-64 package, ensure adequate thermal vias under the exposed pad to dissipate heat. Place decoupling capacitors close to the VDD and VSS pins. Use a solid ground plane to minimize noise. Follow the layout guidelines in the datasheet for the differential RC filters on cell input channels.
Route the daisy-chain communication lines (COMMH/COMML) as differential pairs with controlled impedance. Keep them away from high-current switching paths to avoid noise coupling. Terminate the daisy-chain properly at the end of the chain to ensure reliable communication.
Do not exceed the absolute maximum ratings for the supply voltage. Ensure the cell input voltages are within the specified range. Use proper ESD protection on the communication lines. Verify the pinout against the datasheet before PCB layout to avoid costly mistakes.
