NOTE: 5. BVDSS is the Absolute Maximum Voltage Rating Between Drain and Source Terminal of Each MOSFET Inside Motion SPM

5 product. VPN Should be Sufficiently Less Than This Value Considering the Effect of the Stray Inductance so that VDS Should

Not Exceed BVDSS in Any Case.

6. tON and tOFF Include the Propagation Delay Time of the Internal Drive IC. Listed Values are Measured at the Laboratory

Test Condition, and They Can be Different According to the Field Applications Due to the Effect of Different Printed Circuit

Boards and Wirings. Please see Figure 7 for the Switching Time Definition with the Switching Test Circuit of Figure 7.

7. The peak current and voltage of each MOSFET during the switching operation should be included in the Safe Operating

Area (SOA). Please see Figure 6 for the RBSOA test circuit that is same as the switching test circuit.

8. VTS is only for sensing temperature of module and cannot shutdown MOSFETs automatically.

9. Built in bootstrap diode includes around 15 W resistance characteristic. Please refer to Figure 2.
