Over-voltage Protection Module enabling direct connection of voltage regulators to 5.5 V batteries with standard 1.8 V I/O devices

Key Benefits

  • Implement power networks supporting up to 5.5 V​
  • High voltage protection (> 1.98 V) for LDO & DC/DC​
  • Low BoM Cost: no output capacitor, no extra pin​
  • Generation of low power biasing currents and voltages​
  • Supports up to 6 LDO or DC/DC​
  • Low quiescent current
  • Embedded 5 V I/O pads (based on 1.8 V I/O & 1.8 V HVMOS)
