This grid fault current indicator is an example of a low power design system that shows customers the most efficient approach for system implementation.
The fault indicator unit uses Renesas’ high-performance RA2 MCU series, which includes a 16-bit SAR ADC, 24-bit sigma-delta ADC, COMP, system control, touch control, super low power, etc. In the data collection unit, the RL78/G13 is a standard function MCU with low power and an abundant lineup for general purpose applications. Bluetooth® is used for communication between the two boards. Combined with Renesas’ high performance power and analog solutions, this system can minimize idle quiescent current. This helps save power consumption during standby states.
- Low quiescent power MCU solutions for optimized efficiency
- High performance analog devices for accurate system monitoring
