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.

Shoot-Through Protection

The IRS2608D high-voltage ICs is equipped with shoot-through protection circuitry (also known as cross-conduction

prevention circuitry).
