Chip Enable (CE)

The TPSI310x, TPSI311x, TPSI312x, and TPSI313x family has an active high chip enable, CE. When CE is asserted high and VDDP is present, the device enters its active mode of operation and power transfer occurs from the primary side to the secondary side. When CE is asserted low while VDDP is present, the device enters standby and no power transfer occurs from primary side to the secondary side and VDRV will be asserted low. Over time, VDDH and VDDM fully discharges depending on the amount of loading present on these rails.
