Pin Functions

PIN TYPE DESCRIPTION
NAME DGS DSG
ALERT 3 3 Digital output Overlimit alert, active low, open-drain output
CMPIN 8 6 Analog input Signal input to the comparator
CMPREF 7 5 Analog input Input reference to the comparator
GND 5 — Ground Device ground. Connect the thermal pad to the system ground. See the layout example in Figure 54.
IN– 10 8 Analog input Connect this pin to the load side of the shunt resistor
IN+ 1 1 Analog input Connect this pin to the supply side of the shunt resistor
NC 6 — — Not internal connection to device. This pin can be left floating, grounded, or connected to the supply.
RESET 4 4 Digital input Transparent or latch mode selection input. See the Alert Modes section for a detailed description on pin connections.
VOUT 9 7 Analog output Current-sense amplifier output voltage
VS+ 2 2 Supply Power supply: 2.7 V to 5.5 V
Thermal Pad — Thermal Pad — Ground reference for the device that is also the thermal pad used to conduct heat from the device. Tie this pad externally to ground.
