SLUSCX6B February 2018 – February 2024 UCC21222
PRODUCTION DATA
When the DIS pin is set high, both outputs are shut down simultaneously. When the DIS pin is set low or left open, the UCC21222 operates normally. The DIS circuit logic structure is nearly identical compared to INA or INB, and the propagation delay is similar (see Figure 5-20). The DIS pin is only functional (and necessary) when VCCI stays above the UVLO threshold. It is recommended to tie this pin to GND if the DIS pin is not used to achieve better noise immunity.
