The OB6654 is a highly integrated electromagnetic heating solution. The analog part has built-in IGBT driver, HV_MOS driver and 5V voltage regulator module, which simplifies the peripheral circuit of system design. The digital section contains a fast monolithic 8-bit microcontroller core, a full-featured 8-bit embedded controller that executes all ASM51 instructions with the same instruction settings as the MCS-51.
The OB6654 is available in 20-pin and 16-pin SOP packages.
Typical Applications
Induction cooker, IH rice cooker and other systems
