Switching and Timing Relationships
The relationships between the input and output signals of the IRS2509 are illustrated below in Figures 3, 4. From these figures, we
can see the definitions of several timing parameters (i.e. t ON , t OFF , t R , and t F ) associated with this device.

Deadtime
This family of HVICs features integrated deadtime protection circuitry. The deadtime for these ICs is fixed; other ICs within IR’s HVIC
portfolio feature programmable deadtime for greater design flexibility. The deadtime feature inserts a time period (a minimum
deadtime) in which both the high- and low-side power switches are held off; this is done to ensure that the power switch being turned
off has fully turned off before the second power switch is turned on. This minimum deadtime is automatically inserter whenever the
external deadtime is shorter than DT; external deadtimes larger than DT are not modified by the gate driver. Figure 5 illustrates the
deadtime period and the relationship between the output gate signals.
The deadtime circuitry of the IRS2509 is matched with respect to the high- and low-side outputs. Figure 6 defines the two deadtime
parameters (i.e., DT LO-HO and DT HO-LO ); the deadtime matching parameter (MDT) associated with the IRS2509 specifies the maximum
difference between DT LO-HO and DT HO-LO .
Matched Propagation Delays
The IRS2509 is designed with propagation delay matching circuitry. With this feature, the IC’s response at the output to a signal at
the input requires approximately the same time duration (i.e., t ON , t OFF ) for both the low-side channels and the high-side channels; the
maximum difference is specified by the delay matching parameter (MT). The propagation turn-on delay (t ON ) of the IRS2509 is
matched to the propagation turn-on delay (t OFF ).
