RICOH Electronic Devices introduced the RN5T569, a power management multichannel IC (PMIC) for automotive applications that provide four high-efficiency step-down DC-DC converters, seven low-dropout regulators, four GPIOs, an interrupt controller (INTC), and an I2C-Bus interface. The new IC can customize the power supply voltage and the power on/off sequence to meet user-system with a built-in OTP (One-Time Programmable) memory. The RN5T569 PMIC also provides DVC (Dynamic Voltage Scaling), a thermal shutdown function, and overcurrent protection, and a watchdog timer and provides a power-on/off mode which is controllable individually by GPIOx pins.
