Enable Pin

Setting the EN pin low, i.e. VEN≤0.8V, shuts down both outputs simultaneously. Pull the EN pin high (or left open), i.e. VEN≥2.0V, allows UCC21530-Q1 to operate normally. The EN pin is quite responsive, as far as propagation delay and other switching parameters are concerned, the delay between EN are OUTA and OUTB is about 40ns. The EN pin is only functional (and necessary) when VCCI stays above the UVLO threshold. It is highly recommended to tie EN to VCCI directly to achieve better noise immunity.
