10.1 Layout Guidelines

For the following procedure, see Figure 15 and Figure 16.

  1. Place CVDDCP capacitor close to the device.
  2. Place BAT and PACK RC filters close to the device.
  3. Generally, a typical system using an AFE, MCU, and bq76200 usually have a high-current ground trace/plane and low-current ground plane in the PCB layout. If so, the bq76200 ground should be connected to the low-current ground plane of the PCB layout to remove noise affecting the ENABLE signals.
