Inverter IC series has not guaranteed the output short circuit. If an output short circuit occurs, IC may break.
This IC series has not guaranteed the amount of surge voltage durability. Please use a surge suppressor diode. so that applied voltage becomes within the maximum rating.
The package of three types is used for inverter IC series. These are roughly divided and are divided into a package group called SIP (Single in Line Package) and SOP (Small Outline Package).A classification of a package is as follows.
| SP-23TA, SP-23TB, SP-23TR | |
| FP-28DJ |
Here, the internal structure and composition material of a package about SIP and SOP are indicated. Please refer to Here SIP (PDFformat, 20KB), SOP (PDFformat, 27KB).
Weight is shown in the following table.

The logic circuit which prevents an arm short circuit is built in the ECN306* series, and ECN3053/3054/30531/30541. However, if it takes into consideration till the delay time of an output of operation, a short circuit state cannot be prevented completely. Therefore, in an incoming signal, it is necessary to prepare the dead time with consideration to output delay time. About a setup of a dead time, please refer to Inverter Application Technical Notes Q10.
The over-current detection function attaches the Motor driver IC series.
