Ground
G570 operation when floating or pulled low; must be pulled high externally for G574 operation.
MODE is internally pulled low with a 150k
pulldown resistor.
Logic-level overcurrent. reports output that goes low when an overcurrent condition exists

pulldown resistor.
Logic-level reset input active low. Do not connect if RESET pin is used. The pin is internally
pulled high with a 150k
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 150k
pullup resistor to 5V, if 5V V
CC
exists. And pulled
to 3.3V, if 3.3V V
CC
exists only.
