Renesas Electronics Energy-Efficient Single-Burner Induction Cooktop

Renesas Electronics Energy-Efficient Single-Burner Induction Cooktop delivers the highest efficiency power conversion with differentiating features. These features include rapid and focused heating, operational simplicity, and high reliability. It is important in induction cooking applications that the IGBT controller provides intelligent induction element control. It should give the designer the tools and technical advantages to build a system that is efficient and reliable. The required functions are integrated to simplify the design cycle and produce a volume-manufacturable design that is fast to market at a competitive cost. This 2100W, single-plate induction cooktop design, using the iW248 smart IGBT driver and controller single-chip ASSP offers high-efficiency and high-reliability performance. The design allows the flexibility to adjust the power in ±10W steps, allowing users to cook at the simmering condition. A capacitive touch sensing unit (CTSU) enables robust capacitive touch, which senses properly in wet conditions. Over-temperature detection using three negative temperature coefficient resistors (NTCs) is provided in the design.
