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.
