Power Down

When the discharge-sense (DIS_SENSE) voltage falls below its typical threshold voltage of 1.26 V, all clock output channels follow VGH until VGH falls below its typical falling UVLO threshold voltage of 3.5 V; then all clock output channels and DISCH1 follow VGL1, DISCH2 follows VGL2. Once discharge-sense is triggered the state is latched, to reset and continue normal operation VGH has to fall below the falling UVLO threshold of 3.5 V.

In case the discharge-sense (DIS_SENSE) voltage stays high during power down, all clock output channels follow their input signals until VGH falls below its typical falling UVLO threshold voltage of 3.5 V; then all clock output channels follow VGL1. The discharge channels follow VGL1 and VGL2 all the time.
