PRODUCTION DATA
The logic enable controls the power switch and device supply current. The supply current is reduced to less than 2 μA when a logic high is present on EN or when a logic low is present on EN. A logic low input on EN or a logic high input on EN enables the driver, control circuits, and power switch. The enable input is compatible with both TTL and CMOS logic levels.
