PRODUCTION DATA
The logic enable pin disables the power switch and the bias for the charge pump, driver, and other circuitry to reduce the supply current. The supply current is reduced to less than 1 μA or 2 μA when a logic high is present on EN. A logic zero input on EN restores bias to the drive and control circuits and turns the switch on. The enable input is compatible with both TTL and CMOS logic levels.
