11 Power Supply Recommendations

A proper power-up sequence always should be followed to avoid excessive supply current, bus contention, oscillations, or other anomalies. To guard against such power-up problems, take the following precautions:

  1. Connect ground before any supply voltage is applied.
  2. Power up VCCA.
  3. VCCB can be ramped up along with or after VCCA.
