RL78/G1F Handy Vacuum Cleaner
This Handy Vacuum Cleaner reference design enables switching between two operation levels of suction power: high or low. The sensorless 3-phase BLDC motor is rotated at high speed to provide the appropriate strength of suction for each level. The battery-driven, cordless operation makes vacuuming with one hand a breeze!
This solution features the RL78/G1F which comes with a built-in programmable gain amplifier (PGA), comparator (CMP0), and pulse width modulation (PWM) option unit A (PWMOPA) for overcurrent detection and PWM output-forced cutoff control. With 120-degree conducting control, the 4-input selectable comparator and motor control auxiliary timer can achieve sensorless rotor position detection even when the motor is stopped or rotating at high-speeds exceeding the maximum 50,000rpm.
The ISL94202 Li-ion battery monitor IC's power management provides battery charge and discharge control, current and voltage monitoring, and battery balance control.
