INA303A1IPWR

Texas Instruments · Current Sense Amplifiers · TSSOP-14

INA303A1IPWR from Texas Instruments, in a TSSOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VS power_in Analog power supply, 2.7 V to 5.5 V
2 OUT output Output voltage
3 LIMIT1 input ALERT1 threshold limit input; see the Setting Alert Thresholds section for details on setting the limit threshold
4 REF input Reference voltage, 0 V to VS
5 GND power_in Analog ground
6 LATCH1 input Transparent or latch mode selection input
7 LATCH2 input Transparent or latch mode selection input
8 NC unconnected No internal connection
9 LIMIT2 input ALERT2 threshold limit input; see the Setting Alert Thresholds section for details on setting the limit threshold
10 DELAY input Delay timing input; see the Alert Outputs section for details on setting the delayed alert response for comparator 2
11 ALERT2 tri_state Open-drain output; active-low; underlimit alert for the INA303
12 ALERT1 tri_state Open-drain output, active-low overlimit alert
13 IN- input Connect to load side of the current-sensing resistor
14 IN+ input Connect to supply side of the current-sensing resistor
