INA186A4IDDFR

Texas Instruments · Current Sense Amplifiers · TSOT-23-8

INA186A4IDDFR from Texas Instruments, in a TSOT-23-8. 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 pin, operating from 1.7 V to 5.5 V.
2 ENABLE input Enable pin: driving it to VS turns the device on, driving it to GND turns it off, reducing supply current and placing the output in high-impedance state, and it must be driven externally or connected to VS if unused.
3 REF input Reference input that enables bidirectional current sensing with an externally applied voltage, which must be within GND to VS.
4 GND power_in Analog ground pin.
5 OUT output Analog output giving the gained-up voltage difference from IN+ to IN-, offset by the voltage applied to REF; absolute limit is GND - 0.3 V to (VS) + 0.3 V.
6 NC unconnected No internal connection; can be left floating, grounded, or connected to supply.
7 IN+ input Current-sense amplifier positive input; connect to bus voltage side of sense resistor for high-side applications or to load side for low-side applications.
8 IN- input Current-sense amplifier negative input; connect to load side of sense resistor for high-side applications or to ground side for low-side applications.
