Further, gate-drive input signal differentiation offered across the three devices in the IRS260xD family allows for a wide variety of HO microcontroller options. Higher Reliability The IRS260xD devices are part of the latest family of gate drivers designed to be the most rugged in the market for hard switching environments such as motion control circuits. The typical problem in voltage source inverters with inductive loads (as in the motion control domain) is that the hard switching generates Overall Benefits • Reduced component count because the high-voltage clamping diodes used in other solutions are no longer necessary; • Fewer field returns because the robust IR HVIC does not fail in an unpredictable manner unlike other solutions Input filters have been re-designed to prevent small pulse commands reaching the gates of the switches in the VBUS Q2 VS Undershoot LS2 VS To Load LD1 LO inverter. This is one of the sources of problems in the field and usually it is difficult to find. The typical effect is that sometime inverters return from the field damaged with one destroyed leg without an apparent root cause. The IRS2607 embeds filters that solve this issue. In addition, the IRS260xD family of HVICs offer dedicated UVLO protection for both the floating and fixed bias supplies, cross-conduction prevention logic [not IRS2607D] for shootthrough immunity and matched propagation delay between channels for highest levels of safety.
