Fig. 9 RECOMMENDED MCU I/O INTERFACE CIRCUIT

Note : The setting of RC coupling at each input (parts shown dotted) depends on the PWM control scheme and the

wiring impedance of the printed circuit board.

The DIP-IPM input section integrates a 3.3k

Ω (min) pull-down resistor. Therefore, when using an external

filtering resistor, pay attention to the turn-on threshold voltage.

Wiring inductance should be less than 10nH.

Shunt resistor

Equivalent to the inductance of a copper

pattern in dimension of width=3mm,

thickness=100

µm, length=17mm

Please make the GND wiring connection

as close as possible.
