PIN		TYPE	DESCRIPTION
NO.	NAME	TYPE	DESCRIPTION
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 Section 7.3.3.1 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 Section 7.3.3.1 section for details on setting the limit threshold
10	DELAY	Analog input	Delay timing input; see the Section 7.3.3 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-Q1 and an underlimit alert for the INA303-Q1.
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
