It is suitable for drive of IH jar rice cooker or electromagnetic cooker. n Features

• Turning-on and -off driving capabilities of power element able to be set separately
• Shunt regulator circuit built-in
• Low V CC protection function built-in
• Power-on protective function built-in. At power-on, the output is fixed to “Low ” until the VCC rises to protect the power element from mis-conduction.
• Protective operation signal output It transmits the signal to the control side when any of the abo- ve protective functions are activated.
