Description

The RN5T569 is a power management multi-channel IC (PMIC) for automotive 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 poweron/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.

Application

Power management IC for car accessories including car audio equipment, car navigation system,and etc.
