Electric rice cooker users need mechanical controls and displays that help them prepare meals and avoid shocks or burns. A block diagram shows components Littelfuse makes for controlling heating plates, protecting LED and LCD displays, and preventing unsafe operation. Our solutions include NTC thermistors for temperature sensing, TVS diodes for ESD protection, and reed sensors for lid detection.

A simplified block diagram for a rice cooker motherboard illustrates the need for metal oxide varistors, Schottky diode rectifiers, and triacs. Littelfuse produces each of these overcurrent protection and current switching devices. We also make fuses that protect the solid state switches from overcurrent events.
