概述

RN5T5612 是电源管理IC (PMIC)。
该产品IC配备有4个高效降压型DC/DC转换器、7个LDO稳压器、4个通用I/O (GPIO)、1个中断控制器 (INTC)、和1个I2C 总线接口。使用内置的OTP内存，结合用户系统能够定制电源电压和电源启动时序。
此外，该产品IC还备有DVS (Dynamic Voltage Scaling: 动态电压调节)、热关断、过流保护、看门狗定时器，并可通过 GPIOx 引脚单独控制各DCDC / LDO 的开和关。

应用范围

  • 嵌入式FPGA/SoC解决方案
  • 机顶盒、AI扬声器等通信设备
  • POS机、读码器、平板电脑等工业和商业用手持机
