Overview
The INA250A3QPWRQ1 is a high-side current sense amplifier from Texas Instruments, designed for automotive applications under the AEC-Q100 qualification standard. It operates with a supply voltage range of 2.7 V to 5.5 V and supports common-mode voltages up to 36 V. The device features a fixed gain of 25 V/V, enabling precise measurement of shunt resistor voltage drops. Key electrical characteristics include a maximum gain error of 0.3% and a bandwidth of 400 kHz. It functions within an extended temperature range of -40°C to +125°C and is housed in a TSSOP-16 package.
Feature Summary
- Automotive-grade reliability certified to AEC-Q100 standards for robust performance in vehicle environments.
- High common-mode voltage tolerance allows direct connection to high-side loads without level shifting.
- Precision amplification with low gain error ensures accurate current monitoring across varying load conditions.
Applications
- Battery management systems in electric and hybrid vehicles
- Motor control circuits requiring precise current feedback
- Load switching protection mechanisms
Procurement Notes
Verify the specific suffix 'QPWRQ1' confirms AEC-Q100 automotive qualification and TSSOP-16 packaging. Ensure compatibility with system voltage levels and thermal requirements. Cross-reference official datasheets for pinout and electrical limits before integration. Confirm RoHS compliance status through manufacturer documentation.
Selection Notes
Select this component when automotive certification is mandatory and high-side sensing is required. Compare gain accuracy and bandwidth against application needs. Consider package size constraints and thermal dissipation capabilities relative to other current sense amplifiers in the portfolio.
Part Context
Part of the INA250 family of precision current sense amplifiers. Designed specifically for automotive electronics where reliability and wide common-mode voltage ranges are critical. Complements other TI sensors for comprehensive power management solutions.
Replacement Considerations
Check for direct pin-compatible alternatives within the INA250 series or similar TI automotive current sense amplifiers. Verify that substitute parts meet identical AEC-Q100 qualifications and electrical specifications.
