描述
RL78/G1G microcontrollers have a three-phase complementary PWM timer for brushless DC motor control, a comparator for stopping motor rotation when overcurrent is detected and its 8-bit D/A converter for reference voltage, and a PGA (Programmable Gain Amplifier) for controlling amplification factor by software. The number of components can be reduced. The comparator is over eight times faster than that of previous products, and high-speed overcurrent detection can be performed. Built-in safety features (functions that detect illegal hardware operation) make it possible to satisfy the European home appliance safety standard (IEC 60730). The 0.8-mm pitch QFP lineup also helps reduce solder mounting expenses.
