Shoot-Through Protection
The IRS2334 is equipped with a shoot-through protection circuitry which prevents cross-conduction of the power
switches. Table 1 shows the input to output relationship in the form of a truth table. Note that the HVIC has non-
inverting inputs (the output is in-phase with the respective input).

Under-Voltage Lockout Protection
The IRS2334 HVIC provides under-voltage lockout protection on both the V CC low side and logic fixed power
supply and the VBS high side floating power supply. Figure 8 illustrates this concept by considering the V CC (or
V BS ) plotted over time: as the waveform crosses the UVLO threshold, the under-voltage protection is entered or
exited.
Upon power up, should the V CC voltage fail to reach the V CCUV+ threshold, the gate driver outputs LO and HO will
remain disabled. Additionally, if the V CC voltage decreases below the V CCUV- threshold during normal operation,
the under-voltage lockout circuitry will shutdown the gate driver outputs LO and HO.
Upon power up, should the V BS voltage fail to reach the V BSUV threshold, the gate driver output HO will remain
disabled. Additionally, if the V BS voltage decreases below the V BSUV threshold during normal operation, the under-
voltage 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
