• Thermal shutdown protection

illustrate

This unit is a versatile, programmable power management unit (PMU) optimized for sub-block power solutions. The device integrates two high-efficiency 600 mAh step-down DC/DC converter configurations with dynamic voltage regulation (DVS) 800 mA load via I 2 C, two low-noise analog LDOs, three digital LDOs that can accommodate 300 mA of load current per two low-input low-output (LILO) regulators and one I 2 C is compatible with serial interfaces, allowing the main controller to access internal control registers. The device also features a programmable power-up sequence. LDO regulators offer high PSRR and low noise, making them ideal for power supply to analog and digital loads.

The device can be configured as a module Sub_PMU (e.g., camera/multimedia module) or as a standalone PMU with the power processor itself.
