RN5T5612
Programmable Power Management IC

The RN5T5612 is a power management multi-channel IC (PMIC) for consumer applications.

This IC provides four high-efficiency step-down DCDC converters, seven low-dropout regulators, four GPIOs, an interrupt controller (INTC), and an I²C-Bus interface. This IC can customize the power supply voltage and the power-on/off sequence to meet user-system with using a built-in OTP (One-Time Programmable) memory.

In addition, this IC provides DVS (Dynamic Voltage Scaling), a thermal shut-down function, an overcurrent protection, and a watchdog timer and provides a power-on/off mode which is controllable individually by GPIOx pins.
