FUNCTION
3-Wire Serial Interface Input Clock Line. Referenced to DGND. Connect to DGND if the I 2 C interface is
not used.
Serial Interface Data Line Output. Referenced to DGND. Connect to DGND if the I 2 C interface is not
used.
Serial Interface Data Line Input. Referenced to DGND. Connect to DGND if the I 2 C interface is not
used.
EN Input. Referenced to DGND. Connect EN to V DD externally through a pullup resistor to enable
normal operation. See the Hardware Power-Down section for details.
Slave Address Bits 0, 1, 2, 3 (Respectively). Referenced to DGND. The slave address bits are used
to form bits 3, 2, 1, and 0 of the device address (0:1:0:A3:A2:A1:A0; see Table 3). The slave address
bits are internally pulled up to V DD . Leave them unconnected to use the default device address
(0101111). Connect one or more to DGND to change the device address. The slave address is
latched-in after the device is powered up or after a reset condition.
Digital Low-Side Supply Input. Connect to V EE externally.
Port 3/4 Current-Sense Negative Terminal Input. Use Kelvin-sensing technique in PCB layout for best
accuracy current sensing.
