Overview
The INA180B2QDBVRQ1 is a single-channel, AEC-Q100 qualified current sense amplifier from Texas Instruments. It operates with a supply voltage range of 2.7 V to 5.5 V and supports bidirectional current sensing within a common-mode voltage range of -200 mV to 26 V. The device features a fixed gain of 50 V/V, a gain bandwidth product of 210 kHz, and a maximum input offset voltage of 100 µV. It draws 260 µA of quiescent current and offers a common-mode rejection ratio of 100 dB. Packaged in an SOT-23-5 case, it functions reliably across an operating temperature range of -40°C to +125°C.
Feature Summary
- Supports both low-side and high-side current sensing configurations
- Provides bidirectional measurement capability for accurate current monitoring
- Delivers high precision with low input offset voltage and bias current
Applications
- Automotive battery management systems
- Motor control circuits
- Power distribution units
Procurement Notes
Verify the specific suffix QDBVRQ1 to confirm automotive qualification and package type. Ensure compatibility with the target application's voltage levels and thermal requirements. Cross-reference the datasheet for exact pinout and electrical limits before integration.
Selection Notes
Select this component when a compact SOT-23-5 package is required for automotive current sensing applications. It is suitable for designs needing a fixed gain of 50 V/V with high common-mode rejection. Consider its 260 µA quiescent current for power-sensitive systems.
Part Context
This part belongs to the INA180-Q1 family of current sense amplifiers designed for automotive environments. It shares architectural similarities with other members like the INA180A1QDBVRQ1 but differs in gain and performance specifications. The series is optimized for robust operation in noisy automotive electrical systems.
Replacement Considerations
INA180A1QDBVRQ1 offers similar automotive qualification but provides a different gain setting. Verify that the alternative gain matches the system design requirements before substitution.
