Pinout
The INA194AQDBVRQ1 is a current shunt monitor from Texas Instruments, designed for high-side current sensing applications. It comes in a SOT-23-5 package, which means it has 5 pins.
The main functions of these pins are as follows:
1. V+ (Pin 1): Power supply input pin. Connect this to the positive supply voltage.
2. OUT (Pin 2): Output pin. This is where the voltage proportional to the sensed current is output.
3. GND (Pin 3): Ground pin. Connect this to the system ground.
4. IN- (Pin 4): Negative input pin. Connect this to the low side of the shunt resistor.
5. IN+ (Pin 5): Positive input pin. Connect this to the high side of the shunt resistor.
This device is designed to amplify the small differential voltage across a shunt resistor in order to produce a larger, ground-referenced output voltage, which is proportional to the current flow. It is suitable for automotive applications due to its AEC-Q100 qualification.
