Description

The RN5T5611 is a power management IC (PMIC) for automotive applications. This IC provides two highefficiency step-down DC/DC converters, a low-noise regulator, an interrupt controller (INTC), and I2C-bus interface. Power-supply start and stop sequences can be customized to meet user-system. In addition to the basic power control, this IC provides various protection functions.

Key Benefits

  • Compliance with ASIL-D
  • LDO regulator is provides low output noise, high ripple rejection and fast response characteristics.
  • Flexible selection such as sequence and enable simplifies power sequence control.
  • 2 ch Step-down DC/DC converters operate with 180° turn-on phase shift of the switching transistors.

  • How to Use RN5T5611 Evaluation Board

  • RN5T5611 Series, PMIC Suitable for Automotive Cameras
