Overview
The INA210BQDCKRTL is a bidirectional zero-drift current shunt monitor manufactured by Texas Instruments. It features a fixed gain of 200 V/V and operates on a single power supply ranging from 2.7 V to 26 V. The device supports high-side and low-side measurements with a common-mode voltage range extending up to 26 V. Designed for automotive applications, it meets AEC-Q100 qualification standards and offers an operating temperature range from -40°C to +125°C. The component utilizes a SC-70-6 surface-mount package.
Feature Summary
- Bidirectional measurement capability for accurate current monitoring in both directions
- Zero-drift architecture ensures minimal offset voltage drift over temperature variations
- Automotive-grade reliability compliant with AEC-Q100 qualification requirements
Applications
- Automotive battery management systems
- High-side and low-side current sensing in vehicle electronics
- Motor control current monitoring
Procurement Notes
Verify the specific suffix 'BQ' indicates automotive grade and 'RTL' denotes tape-and-reel packaging configuration. Confirm the datasheet revision matches the production batch. Ensure the SC-70-6 footprint aligns with the target PCB design. Check for any recent PCN notices regarding assembly site changes or material updates.
Selection Notes
Select this component when automotive qualification is mandatory and bidirectional sensing is required. The fixed 200 V/V gain suits applications expecting small shunt voltages. Consider the SC-70-6 package size constraints. Verify that the 26 V common-mode limit covers the maximum system voltage. Compare power consumption against other zero-drift options if battery life is critical.
Part Context
This part belongs to the INA210 series of current shunt monitors. It shares architectural similarities with the INA213 and INA214 but differs in interface and gain configurations. The series emphasizes precision and stability for industrial and automotive environments. The BQ suffix specifically identifies the automotive qualified variant within the broader product family.
Replacement Considerations
INA210BQDCKR is the non-reel equivalent. INA213AIDCKR offers similar performance with different gain options. Verify pin compatibility before substitution.
