Matched Propagation Delays
The IRS233(0,2)(D) family of HVICs is designed with propagation delay matching circuitry.

side channels and the high-side channels. Additionally, the propagation delay for each low-side channel is matched when
compared to the other low-side channels and the propagation delays of the high-side channels are matched with each other.

Input Logic Compatibility
The inputs of this IC are compatible with standard CMOS and TTL outputs. The IRS233(0,2)(D) family has been designed to
be compatible with 3.3 V and 5 V logic-level signals. The IRS233(0,2)(D) features an integrated 5.2 V Zener clamp on the
HIN, LIN, and ITRIP pins. Figure 6 illustrates an input signal to the IRS233(0,2)(D), its input threshold values, and the logic
state of the IC as a result of the input signal.
Undervoltage Lockout Protection
This family of ICs provides undervoltage lockout protection on both the V

Upon power-up, should the V
voltage decreases below the V
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
decreases below the V
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.
