OPM-Angel-AR-ref-1.9-5.5.01_TSMC_55_uLPeF is an Over-voltage Protection Module companion for regulators in TSMC 55uLPeF enabling over-voltage operation while using standard process 3.3 V devices.

Key Benefits

  • Over-voltage protection biasing for embedded regulators
  • Avoids expensive solutions while enabling direct baterry connection.
  • Built-in over-voltage protection (up to 5.5 V) using 3.3 V transistors
  • Over-voltage power range: 1.9 V to 5.5 V
  • Fixed 2.6 V regulated output voltage with 10% accuracy
  • Low-leakage for SoC retention mode
  • Low power mode quiescent current (at ILOAD = 0 mA): 400 nA
  • Low noise enhancement: improve the network PSRR up to 40 dB when input supply is higher than 2.8 V
  • Behavioral models: ease of integration in SoC and optimization of Power Management Network (PMNet) using models to verify mode transitions as well as noise propagation
