VPP
SHDN (Pins 2, 8): Shutdown Outputs. When the output is
high, the external 12V regulator can be shut down to
conserve power consumption.
EN0, EN1 (Pins 3, 4, 9, 10): Logic inputs that control the
voltage output on VPP
compatible with TTL/CMOS levels. Refer to the Truth
Table.
V
MOSFET gate driver DRV3. ESD protection device limits
input excursions to 0.6V below ground.

MOSFET gate driver DRV5. ESD protection device limits
input excursions to 0.6V below ground.

DRV5, DRV3 (Pins 13, 14, 19, 20): Gate driver outputs
that control the external MOSFETs that switch the V
of card slot to Hi-Z, 3.3V, or 5V.
V
These pins supply the power to the control logic and the
charge pumps and must be continuously powered.
GND (Pins 16, 22): Ground Connections.
