11.1 Layout Guidelines

Use the following layout guidelines:

  1. Ensure the RC filters for the Vx pins and VDD pin are placed as close as possible to the target terminal, reducing the tracing loop area.
  2. The capacitor for REG should be placed close to the device terminals.
  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.
