n Overview
The AN6721is an IC with driver which drives the IGBT of large
power element and various protective functions. 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 VCC 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.
