PIN DEFINITION
Voltage regulator output, proper decoupling cap should be connected to this pin.
Current sense minus input
Current sense plus input
VBus voltage sense
I²C level shifter power supply, this pin should be connected to VCC pin if level shifters are not
used.
Chip power supply
Voltage regulator input. This pin should be connected to ground in case voltage regulator is
not used.
Auxiliary port single-ended input
I²C address input
I²C address input
I²C address input
SMBus/I²C clock input
Ground
External ADC clock input or CPU interrupt signal. It is used as CPU interrupt signal only when
this pin is not configured as external clock input.
SMBus Alert1, open collector output
SMBus/I²C data
