PMIC

Our multi-channel PMICs are high-density power management system ICs. The flexible sequence control and output voltages enable our PMICs to correspond to multi-core application processors which require high-accuracy sequence control functions. For applications powered by a 1-cell Li-ion battery, we recommend the RN5T618 and the RC5T619, PMICs with a charging function and a fuel gauge.

*DVS (Dynamic Voltage Scaling), it allows the output voltages to be programmed through I2C during power on.

*The RN5T5612 is a consumer-grade PMIC even usable for industrial equipment.


Optimal PMICs and Support for Your Applications

A power management multi-channel IC contains multiple DC/DC switching regulators, LDO linear regulators, and various power management functions in a single chip, and is usually abbreviated as PMIC.

In general, a PMIC is made to be optimized for a specific system by integrating multiple power supplies necessary for the system in a single chip. Also by controling power-supply on/off sequences, a PMIC can not only optimize power consumption but also protect FPGAs and SoCs from malfunction caused by such as inrush current and latch-up, or from being damaged by wrong power input orders.
