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

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 IRS26310D is equipped with shoot-through protection circuitry (also known as cross-conduction prevention
circuitry).
