Undervoltage Lockout Protection
This family of ICs provides undervoltage lockout protection on both the V

time and as the waveform crosses the UVLO threshold (V

fault condition and shutdown the high- and low-side gate drive outputs, and the FAULT pin will transition to the low
state to inform the controller of the fault condition.
Upon power-up, should the V
voltage decreases below the V
condition, and shutdown the high-side gate drive outputs of the IC.
The UVLO protection ensures that the IC drives the external power devices only when the gate supply voltage is
sufficient to fully enhance the power devices. Without this feature, the gates of the external power switch could be
driven with a low voltage, resulting in the power switch conducting current while the channel impedance is high; this
could result in very high conduction losses within the power device and could lead to power device failure.

The IRS26302DJ is equipped with shoot-through protection circuitry (also known as cross-conduction prevention
circuitry).
