Pin Functions

PIN TYPE DESCRIPTION
NO. NAME
1 VS Analog Power supply, 2.7 V to 5.5 V
2 OUT Analog output Output voltage
3 LIMIT1 Analog input ALERT1 threshold limit input; see the Setting Alert Thresholds section for details on setting the limit threshold
4 REF Analog input Reference voltage, 0 V to VS
5 GND Analog Ground
6 LATCH1 Digital input Transparent or latch mode selection input
7 LATCH2 Digital input Transparent or latch mode selection input
8 NC — No internal connection
9 LIMIT2 Analog input ALERT2 threshold limit input; see the Setting Alert Thresholds section for details on setting the limit threshold
10 DELAY Analog input Delay timing input; see the Alert Outputs section for details on setting the delayed alert response for comparator 2
11 ALERT2 Analog output Open-drain output; active-low. This pin is an overlimit alert for the INA302 and an underlimit alert for the INA303.
12 ALERT1 Analog output Open-drain output, active-low overlimit alert
13 IN– Analog input Connect to load side of the current-sensing resistor
14 IN+ Analog input Connect to supply side of the current-sensing resistor
