Description

The TIDA-01559 is a Human Machine Interface (HMI) reference design that uses the MSP430FR2522 MCU and LP5569 device, and can achieve extremely low standby power consumption and offload the resources of the MCU with LED engine control. This solution can be used anywhere a low-power consuming HMI with good EMI performance and moisture immunity is required.  Examples are a kitchen exhaust hood, cooker top, and refrigerator.

Features
  • Minimum MCU loading when running preset lighting pattern
  • Lower system current consumption through LP5569 engine control
  • Extra low quiescent current during standby mode
  • Full diagnostic and protection
  • Good performance moisture immunity
