DESCRIPTION
I 3.3V VCC input for card power
I 5V VCC input for card power and/or chip power
I 12V VPP input for card power
O Switched output that delivers 0V, 3.3V, 5V or high impedance to card
O Switched output that delivers 0V, 3.3V, 5V, 12V or high impedance to card
O Switched output that delivers 0V, 3.3V, 5V or high impedance
O Switch output that delivers 0V, 3.3V, 5V, 12V or high impedance
Ground
I 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.
O Logic-level overcurrent. reports output that goes low when an overcurrent condition exists
I Logic-level reset input active high. Do not connect if RESET pin is used. RESET is internally
pulled low with a 150kΩ pulldown resistor.
I 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 VCC exists. And pulled to 3.3V, if 3.3V VCC
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 VCC exists. And pulled
to 3.3V, if 3.3V VCC exists only.
