Inverter IC Comparisons

Q1.What is the difference between ECN3030/3031/3035/3036?

The value of reference voltage for over current detection(Vref) and output device breakdown voltage (VSM) is different as shown below.

	AC115V system		AC230V system
	ECN3030	ECN3031	ECN3035	ECN3036
Vref(typ.)	0.5V	1.23V	1.25V	0.5V
VSM	250V		500V

Q2.What is the difference between ECN3035 and 3053/30531?

The power supply applying method and input system of an upper arm drive circuit mainly differs from each other. ECN3035/3036 is fundamentally designed on the basis of the drive circuit except IGBT in single chip inverter IC series. Therefore, the control system has adopted 120 degrees commutation mode. It is the best for a drive of DC Brushless motor which exceeds the applicable capacity of single chip inverter IC especially. On the other hand, ECN3053/30531 drives six output devices by six inputs signal. It is the best for the system which performs an inverter drive by 180 degrees commutation mode especially.

	ECN3035	ECN3053/ECN30531
The upper arm power supply apply method	Charge pump system	Bootstrap system
Input system	VSP inputs	6 inputs
