Note:

, please refer to Figure 4 in page 5.
2. BV
DSS
is the absolute maximum voltage rating between drain and source terminal of each FRFET inside SPM
®
. V
PN
should be sufficiently less than this value considering the
effect of the stray inductance so that V
DS
should not exceed BV
DSS
in any case.
3. t
ON
and t
OFF
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 applcations due to the effect of different printed circuit boards and wirings. Please see Figure 5 for the switching time definition with the switching test circuit of Figure 6.
4. The peak current and voltage of each FRFET during the switching operation should be included in the safe operating area (SOA). Please see Figure 6 for the RBSOA test cir-
cuit that is same as the switching test circuit.

Note:
(1) It is recommended the bootstrap diode D
1
to have soft and fast recovery characteristics with 500-V rating
(2) Parameters for bootsrap circuit elements are dependent on PWM algorithm. For 15 kHz of switching frequency, typical example of parameters is shown above.
(3) RC coupling(R
5
and C
5
) at each input (indicated as dotted lines) may be used to prevent improper input signal due to surge noise. Signal input of SPM
®
is compatible with
standard CMOS or LSTTL outptus.
(4) Bold lines should be short and thick in PCB pattern to have small stray inductance of circuit, which results in the reduction of surge voltage. Bypass capacitors such as C
1
, C
2
and C
3
should have good high-frequency characteristics to absorb high-frequency ripple current.
