[C] Under-Voltage Protection (Upper-side, UVDB)

c1. Control supply voltage rises : After the voltage reaches UVDBr, the circuits start to operate when next input is applied.

c2. Normal operation : IGBT ON and carrying current.

c3. Under voltage trip (UVDBt).

c4. IGBT OFF in spite of control input signal level, but there is no FO signal output.

c5. Under voltage reset (UVDBr).

c6. Normal operation : IGBT ON and carrying current.

Note : RC coupling at each input (parts shown dotted) may change depending on the PWM control scheme used in

the application and the wiring impedance of the application’s printed circuit board.

The DIP-IPM input signal section integrates a 2.5kΩ(min) pull-down resistor. Therefore, when using a external

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

Please make the wiring connection

of shunt resistor to GND as short as

possible.

For 3 shunt resistors connection, please refer to Fig.9.
