Electrical Characteristics (TJ = 25°C, VCC = VBS = 15 V unless otherwise specified.)
Inverter Part (each MOSFET unless otherwise specified.)
Control Part (each HVIC unless otherwise specified.)
Bootstrap Diode Part (each bootstrap diode unless otherwise specified.)
2nd Notes:
1. BVDSS is the absolute maxi mum voltage rating between drain and source terminal of each MOSFET inside Motion SPM® 5 product. VPN should be sufficient ly less than this
value consideri ng the ef f ect of the str ay inductance so that VPN should not exceed BVDSS in any case.
2. tON and tOFF include the propagation delay 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 6 for the switching time definition with the switching test circuit of Figure 7.
3. The peak current and voltage of each MOSFET during the switching operation should be included in the Safe Operating Area (SOA). Please see Figure 7 for the RBSOA test
circuit that is same as the switching test circuit.
4. Vts is only for sensing-temperature of modu l e and can not shut down MOSFETs automati ca ll y.
5. Built-in bootstrap diode includes around 15 Ωresistance characteristic. Please refer to Figure 2.
