Docking stations for robotic vacuums and other household robots double as battery chargers. A block diagram shows which electronic components Littelfuse can supply to help ensure safe and efficient charging. Our solutions include Schottky diode rectifiers for ac–dc conversion, NTC thermistors to prevent overheating, and overvoltage protection devices such as metal oxide varistors and TVS diodes.

Electronic solutions Littelfuse provides for motor drives in robotic vacuums and other household robots appear in this block diagram. Our products include resettable PPTC devices to ensure overcurrent protection to circuits and NTC thermistors to prevent excess heat from damaging brushless dc (BLDC) suction and stepper motors. We also supply TVS diodes to bolster overvoltage protection.

User interfaces, sensors, and displays for robotic vacuums and other household robots require ESD and overvoltage protection. A block diagram shows how TVS diodes and TVS diode arrays made by Littelfuse provide that protection to LCD and LED screens, USB ports, audio inputs and outputs, and wireless communication units. We also supply reed switches and actuator magnets for presence sensors.
