Datasheet 2ED21091S06F (Infineon) - 10

2ED21091S06F 650 V half bridge gate driver with integrated bootstrap diode 5.3 Deadtime This family of HVICs features integrated deadtime protection circuitry. The deadtime is programmable for 2ED21091S06F, it is 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 ful y turned off before the second power switch is turned on. This minimum deadtime is automatically inserted whenever the external deadtime is shorter than interal deadtime; external deadtimes larger than internal deadtime are not modified by the gate driver. Figure 8 illustrates the deadtime period and the relationship between the output gate signals. The deadtime circuitry of 2ED21091S06F is matched with respect to the high- and low-side outputs. Figure 8 defines the two deadtime parameters (i.e., DTLO-HO and DTHO-LO); the deadtime matching parameter (MDT) associated with the 2ED21091S06F specifies the maximum difference between DTLO-HO and DTHO-LO. Figure 8 Deadtime matching waveform definition 5.4 Matched propagation delays The 2ED21091S06F 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., tON, tOFF) 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 (tON) of the 2ED21091S06F is matched to the propagation turn- off delay (tOFF).
