Overview
The INA210BQDCKRQ1 is a bidirectional, zero-drift current shunt monitor from Texas Instruments. It features a fixed gain of 200 V/V and operates with a supply voltage range of 2.7V to 26V. The device supports high-side or low-side measurements with a common-mode voltage range of -300mV to 26V. Key electrical parameters include a maximum input offset voltage of 5µV, a gain error of 0.5%, and a power supply current of 115µA. It offers a gain-bandwidth product of 14kHz and a CMRR of 120dB. 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 voltages
- Bidirectional capability allows detection of current flow in both directions relative to ground
- Automotive qualification meets AEC-Q100 reliability standards for harsh environments
Applications
- Automotive battery management systems
- High-side current monitoring in vehicle power distribution
- Low-side current sensing in automotive control modules
Procurement Notes
Verify the specific suffix 'Q1' confirms AEC-Q100 automotive qualification status. Ensure the package type matches the required SC-70-6 footprint. Confirm the gain setting corresponds to the B variant specifications. Check moisture sensitivity levels for proper storage and handling procedures during assembly.
Selection Notes
Select this component when automotive reliability is required alongside precise bidirectional current measurement. The fixed 200 V/V gain suits applications with larger shunt resistors or lower expected currents. Consider the 26V common-mode limit for standard automotive bus architectures. Evaluate the 115µA quiescent current against system power budget constraints.
Part Context
This part belongs to the INA21x family of zero-drift current shunt monitors. It shares architectural similarities with other members like the INA210 and INA213 but differs in gain and automotive qualification. The family is designed for high-accuracy sensing where drift over temperature must be minimized without external calibration.
Replacement Considerations
INA210BIDCKT is a non-automotive equivalent with identical electrical performance but lacks AEC-Q100 certification. INA213BQDCKRQ1 offers higher accuracy (0.02% gain error) and lower offset (1µV) while maintaining automotive qualification.
