INA199A2DCKR Typical application Circuitry

INA199A2DCKR

INA199A2DCKR is a precision, low-power, voltage-output, current-shunt monitor from Texas Instruments. It is intended to provide a proportional voltage in response to voltage drops across shunt resistors, which are used to detect current in systems. This device is widely utilized in battery management, power management, and overcurrent protection applications due to its high accuracy and wide input common-mode voltage range.

Application Scenarios

INA199A2DCKR is ideally suited for applications like power supply monitoring, battery charging systems, and load detection. It is also used in portable devices for current monitoring and in automotive systems for battery management.

Parameter Features

- High Accuracy: Ensures precise current measurement for effective system monitoring and control.

- Broad Input Compatibility with both high- and low-side current sensing systems is made possible by the common-mode voltage range.

- Low Quiescent Current: This feature reduces power consumption, which makes it perfect for battery-operated devices.

Circuit Connection in a Specific Application Scenario

Consider a battery charging system as an application for the INA199A2DCKR. Here's a detailed explanation of the circuit connection:

- Power Supply Connection: Connect the V+ pin (pin 5) of the INA199A2DCKR to the system power supply. This supply should be within the operating voltage range of the IC to ensure proper functionality.

- Shunt Resistor Integration: Connect a shunt resistor between the positive terminal of the battery and the charging circuit. The INA199A2DCKR's IN+ pin (pin 6) is connected to the side of the shunt resistor closer to the battery, and the IN- pin (pin 4) to the other side of the shunt resistor.

- Output Voltage Monitoring: The OUT pin (pin 1) of the INA199A2DCKR provides a voltage output proportional to the current through the shunt resistor. This pin should be connected to an analog input of a microcontroller or an ADC for current monitoring.

- Ground Connection: To ensure precise readings, make sure the INA199A2DCKR's GND pin (pin 2) is connected to the system ground.

Design Considerations

When designing circuits with the INA199A2DCKR, several important aspects need to be taken into account:

- Shunt Resistor Selection: Choose a shunt resistor with an appropriate value to ensure accurate current measurement without introducing significant power loss in the charging path.

- Common-Mode Voltage: Ensure that the voltage across the shunt resistor falls within the common-mode voltage range of the INA199A2DCKR to maintain accuracy.

- Signal Filtering: Consider adding filtering components at the output to reduce noise, especially in noisy environments or when measuring low currents.

- Thermal Considerations: Pay attention to the power dissipation across the shunt resistor and the INA199A2DCKR, and consider heat sinking if necessary to maintain temperature within safe limits.

Implementing the INA199A2DCKR in a battery charging system involves precise connections and considerations around the shunt resistor, common-mode voltage, and thermal management to ensure accurate and reliable current monitoring for effective battery management.
