Layout Guidelines

  1. Ensure the RC filters for the V1 and VDD pins are placed as close as possible to the target terminal, reducing the tracing loop area.
  2. The VSS pin should be routed to the CELL– terminal.
  3. Ensure the trace connecting the fuse to the gate, source of the NFET to the Pack is sufficient to withstand the current during a fuse blown event.
