NFC Power Management Unit (1.08 – 1.32 V output voltage, 50 nA output current)

130GF_PMU_01 is a Power Management Unit (PMU) block designed to supply embedded integrated circuits with stable and precise voltage, current and clock frequency. IP should derive it’s operating power from rectifier or external DC voltage source (Battery assisted operation).
PMU block consists of:
- DC Limiter (shunt);
- Capless low drop out voltage regulator (LDO);
- Reference current source;
- Power-On-Reset module (POR);
- 2 MHz oscillator.
The DC limiter has a built-in diode with a low voltage drop to prevent the discharge of the storage capacity back into the rectifier. The oscillator has frequency control inputs to compensate for process variation.
