INA199B1DCKT

Current Regulation/Management Overview

The INA199B1DCKT is a bidirectional current sense amplifier from Texas Instruments, housed in a SC-70-6 surface-mount package. It operates on a single supply voltage ranging from 2.7 V to 26 V with a typical quiescent current of 65 µA. The device features a fixed gain of 20 V/V and offers high precision with an input offset voltage of 5 µV and a gain error of 0.03%. It provides a common-mode rejection ratio (CMRR) of 120 dB and supports a bandwidth of 80 kHz. The operational temperature range extends from -40°C to +125°C.

Current Regulation/Management Feature Summary

• Bidirectional sensing capability for both high-side and low-side monitoring applications
• Zero-drift architecture ensuring minimal input offset voltage drift over temperature
• High common-mode rejection ratio for accurate measurements in noisy environments

Current Regulation/Management Applications

• Battery management systems
• Industrial process control
• Power supply output monitoring

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DCKT' confirms the tape-and-reel packaging format required for automated assembly processes. Confirm that the B1 variant matches the intended gain accuracy specifications for the design. Ensure compatibility with the target PCB footprint for the SC-70-6 package. Validate RoHS compliance status against current regulatory requirements for the destination market.

Current Regulation/Management Selection Notes

Select this component when bidirectional current measurement is required within a wide common-mode voltage range. The zero-drift technology makes it suitable for precision applications where temperature stability is critical. Consider the SC-70-6 package size for space-constrained designs. Evaluate the 20 V/V gain against the expected signal levels to ensure optimal resolution without saturation.

Current Regulation/Management Part Context

This part belongs to the INA199 family of current sense amplifiers, which are designed for high-precision monitoring. The family includes variants with different gains and accuracies, such as the A1 and C3 models. The INA199 series is characterized by its low power consumption and robust performance in industrial and automotive environments.

Current Regulation/Management Replacement Considerations

INA199A1DCKR: Offers similar functionality but with different gain accuracy specifications. INA199C3DCKT: Provides alternative gain settings while maintaining the same package and electrical characteristics.
