Overview
The INA213CQDCKRQ1 is a single-channel, bidirectional zero-drift current shunt monitor manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.7 V to 26 V and consumes a maximum of 100 µA. The device features a fixed gain of 50 V/V and an input offset voltage of 5 µV. It supports a common-mode voltage range of -100 mV to 26 V with a common-mode rejection ratio of 140 dB. The component is qualified under AEC-Q100 standards for automotive applications and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Zero-drift architecture ensures low offset voltage for accurate sensing across small shunt voltage drops
- Bidirectional capability allows detection of current flow in both directions relative to ground
- High common-mode rejection ratio maintains signal integrity despite high common-mode voltages
Applications
- Automotive battery monitoring systems
- Load switch control circuits
- Current limiting protection mechanisms
Procurement Notes
Verify the specific suffix CQDCKRQ1 against the official datasheet to confirm the fixed gain value and package type. Ensure the procurement channel provides valid AEC-Q100 certification documentation. Confirm that the operating environment remains within the specified -40°C to +125°C temperature range. Validate power supply constraints between 2.7 V and 26 V before integration.
Selection Notes
Select this component when precise low-voltage drop measurement is required in automotive environments. The zero-drift technology minimizes calibration needs compared to standard amplifiers. Consider the fixed gain limitation and ensure it matches the expected shunt voltage range. Verify compatibility with the system's common-mode voltage levels up to 26 V.
Part Context
This part belongs to the INA21x family of current shunt monitors designed for high-precision applications. The series utilizes chopper stabilization to achieve zero-drift performance. These devices are optimized for space-constrained designs using compact SC-70 or UQFN packages. The family targets industrial and automotive sectors requiring reliable current monitoring.
Replacement Considerations
Check the INA213BQDCKRQ1G4 for alternative gain options within the same automotive-qualified series. Verify pinout compatibility if substituting with other INA21x variants.
