Design Notes
The HTQFP (PAP) package with 64 pins requires proper thermal management. Ensure adequate PCB copper area for heat dissipation, especially in automotive environments with high ambient temperatures. The exposed thermal pad (if present) should be connected to the ground plane with thermal vias to improve heat transfer.
For cell input channels, use simple, low-voltage differential RC filters as recommended by TI. Keep filter components close to the IC pins to minimize noise coupling. Use a dedicated ground plane under the device to reduce parasitic inductance and ensure accurate measurements.
Avoid exceeding the maximum cell voltage or temperature ratings. The daisy-chain communication interface must be properly terminated with a capacitor network to ensure reliable data transmission. Pay attention to the differential filter design to maintain measurement accuracy.
Compliance Information
