outputs during over temperature period, however, the minimum pulse width is 20µs.
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 3.3kΩ (min) pull-down resistor. Therefore, when using an external
filtering resistor, pay attention to the turn-on threshold voltage.
