IGBT Driver

The internal circuit of the IGBT driver is shown in Figure 20:

Figure 20. IGBT Driver circuit

The IGBT driver is enable once the charge pump is switched on and the voltage on pin V5V has reached 4V (to guar-

antee at least 4V driving signal for the IGBT).

The IGBT driver includes all required resistors and pulldowns to operate the IGBT without any external circuitry

3

. Do

not add any external pulldown resistor on pin IGBT_GATE.

3. Exception: If the Sanyo IGBT TIG058E8 is used, add a series resistor of 50

Ω for the gate drive. For Rene-

sas RJP4006AGE add a series resistor of 68

Ω.
