IPPIN vs VPPIN

LTC1314

VPPIN (Pin 1): 12V Power Input.

NC (Pin 2): Not Connected.

SHDN (Pin 3): Shutdown Output. When the output is high,

the external 12V regulator can be shut down to conserve

power consumption.

EN0, EN1 (Pins 4, 5): Logic inputs that control the voltage

output on VPPOUT. The input thresholds are compatible

with TTL/CMOS levels. Refer to Truth Table.

VCC0 (Pin 6): Logic input that controls the state of the

MOSFET gate driver DRV3. ESD protection device limits

input excursions to 0.6V below ground.

VCC1 (Pin 7): Logic input that controls the state of the

MOSFET gate driver DRV5. ESD protection device limits

input excursions to 0.6V below ground.

DRV5, DRV3 (Pins 8, 9): Gate driver outputs that control

the external MOSFETs that switch the VCC pin of card slot

to Hi-Z, 3.3V, or 5V.

VDD (Pin 10): Positive Supply, 4.5V ≤ VDD ≤ 5.5V. This pin

supplies the power to the control logic and the charge

pumps and must be continuously powered.

GND (Pin 11): Ground Connection.

VPPOUT (Pin 12): Switched output that provides 0V, 3.3V,

5V, 12V, or Hi-Z to the VPP pin of the card slot. Refer to

Truth Table.

NC (Pin 13): Not Connected.

VCCIN (Pin 14): 5V or 3.3V Power Input.
