Figure 9. Recommended MCU I/O Interface Circuit
3rd Notes:
1. RC coupling at each input (parts shown dotted) might change depending on the PWM control scheme in the application and the wiring impedance of the application’s printed
circuit board. The Motion SPM ? 3 Product input signal section integrates a 3.3 k ? ( typ.) pull-down resistor. Therefore, when using an external filtering resistor, pay attention to
the signal voltage drop at input terminal.
2. The logic input works with standard CMOS or LSTTL outputs.
These values depend on PWM control algorithm.

3rd Notes:
3. It would be recommended that the bootstrap diode, D BS , has soft and fast recovery characteristics.
4. The ceramic capacitor placed between V CC - COM should be over 1 ? F and mounted as close to the pins of the Motion SPM 3 product as possible.
