Description
The IRS26072D is a high voltage, high speed power MOSFET and IGBT driver with independent high and low side referenced output channels. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. Logic inputs are compatible with CMOS or LSTTL outputs, down to 3.3 V. The output drivers feature a high-pulse current buffer stage designed for minimum driver cross-conduction. The floating channel can be used to drive N-channel power MOSFETs or IGBTs in the high side configuration up to 600 V.

IGBT/MOSFET Gate Drive The IRS26072D HVIC is designed to drive high side and low side MOSFET or IGBT power devices. Figures 1 and 2 show the definition of some of the relevant parameters associated with the gate driver output functionality. The output current that drives the gate of the external power switches is defined as IO. The output voltage that drives the gate of the external power switches is defined as VHO for the high side and VLO for the low side; this parameter is sometimes generically called VOUT and in this case the high side and low side output voltages are not differentiated.

Figure 3: Switching time waveforms
During interval A of Figure 4 the HVIC receives the command to turn on both the high and low side switches at the same time; correspondingly, the high and low side signals HO and LO turn on simultaneously.

Matched Propagation Delays The IRS26072D HVIC is designed for propagation delay matching. With this feature, the input to output propagation delays tON, tOFF are the same for the low side and the high side channels; the maximum difference being specified by the delay matching parameter MT as defined in Figure 6.

Input Logic Compatibility The IRS26072D HVIC is designed with inputs compatible with standard CMOS and TTL outputs with 3.3 V and 5 V logic level signals. Figure 7 shows how an input signal is logically interpreted.
Figure 7: HIN & LIN input thresholds
Under-Voltage Lockout Protection The IRS26072D HVIC provides under-voltage lockout protection on both the VCC low side and logic fixed power supply and the VBS high side floating power supply. Figure 8 illustrates this concept by considering the VCC (or VBS) plotted over time: as the waveform crosses the UVLO threshold, the under-voltage protection is entered or exited. Upon power up, should the VCC voltage fail to reach the VCCUV+ threshold, the gate driver outputs LO and HO will remain disabled. Additionally, if the VCC voltage decreases below the VCCUV- threshold during normal operation, the under-voltage lockout circuitry will shutdown the gate driver outputs LO and HO. Upon power up, should the VBS voltage fail to reach the VBSUV threshold, the gate driver output HO will remain disabled. Additionally, if the VBS voltage decreases below the VBSUV threshold during normal operation, the undervoltage lockout circuitry will shutdown the high side gate driver output HO.

The UVLO protection ensures that the HVIC drives external power devices only with a gate supply voltage sufficient to fully enhance them. Without this protection, the gates of the external power switches could be driven with a low voltage, which would result in power switches conducting current while with a high channel impedance, which would produce very high conduction losses possibly leading to power device failure.

Truth Table: Under-Voltage lockout Table 2 provides the truth table for the IRS26072D HVIC. The 1 line shows that for VCC below the UVLO threshold both the gate driver outputs LO and HO are disabled. After VCC returns above VCCUV, the gate driver outputs return functional. The 2 line shows that for VBS below the UVLO threshold, the gate driver output HO is disabled. After VBS returns above VBSUV, HO remains low until a new rising transition of HIN is received. The last line shows the normal operation of the HVIC.
