Key Differentiators
- ASIL-D functional safety compliance (vs BQ79616PAPRQ1)
- Pin-to-pin compatibility across channel options (vs BQ79718-Q1)
- High-accuracy 16S measurement (vs BQ79712-Q1)
Design Notes
For high-voltage BMS applications, the BQ79716B-Q1's HTSSOP-20 (PAP) package requires a thermal pad connected to ground. Place a 0.1uF decoupling capacitor close to each VDD pin and a 10uF bulk capacitor. The daisy-chain interface should be routed with proper isolation to prevent noise coupling.
Do not exceed the maximum cell voltage rating. Ensure the ADC input filters are properly sized to reduce noise. When using the integrated balancer, confirm the balancing current does not cause excessive thermal rise.
The HTSSOP-20 has a thermal pad that must be soldered to a large copper region for heat dissipation. In a 16S BMS, the device's power dissipation is low, but balancing currents can produce heat. Use vias to the ground plane for thermal relief.
