DESCRIPTION
5V V
CC
input for card power and/or chip power
12V V
PP
input for card power
Switched output that delivers 0V, 3.3V, 5V or high impedance to card
Switched output that delivers 0V, 3.3V, 5V, 12V or high impedance to card
Switched output that delivers 0V, 3.3V, 5V or high impedance
Switch output that delivers 0V, 3.3V, 5V, 12V or high impedance
Ground
G570 operation when floating or pulled low; must be pulled high externally for G574 operation.
MODE is internally pulled low with a 150kΩ pulldown resistor.
Logic-level overcurrent. reports output that goes low when an overcurrent condition exists
Logic-level reset input active high. Do not connect if
RESET
pin is used. RESET is internally
pulled low with a 150kΩ pulldown resistor.
Logic-level reset input active low. Do not connect if RESET pin is used. The pin is internally
pulled high with a 150kΩ pullup resistor to 5V, if 5V V
CC
exists. And pulled to 3.3V, if 3.3V V
CC
exists only.

Logic-level active low input sets the G574 to standby mode and sets all current limits to 50mA.
The pin is internally pulled high with a 150kΩ pullup resistor to 5V, if 5V V
CC
exists. And pulled
to 3.3V, if 3.3V V
CC
exists only.
