Figure 3. Recommended MCU Interface and Bootstrap Circuit with Parameters
3rd Notes:
1. Parameters for bootstrap circuit elements are dependent on PWM algorithm. For 15 kHz of switching frequency, typical example of parameters is shown above.
2. RC-coupling (R 5 and C 5 ) and C 4 at each input of Motion SPM 5 product and MCU (Indicated as Dotted Lines) may be used to prevent improper signal due to surge-noise.
3. 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.

3rd Notes:
4. Attach the thermocouple on top of the heat-sink of SPM 5 package (between SPM 5 package and heatsink if applied) to get the correct temperature measurement.
