What is PINA293A1QDBVRQ1 used for?
The PINA293A1QDBVRQ1 is engineered for high-side current sensing in automotive battery management systems (BMS), electric vehicle traction motor drives, and 48V mild-hybrid powertrain current monitoring where the shunt resistor voltage sits 110V above ground. Its 140 dB minimum CMRR enables accurate millivolt-level shunt voltage measurement despite large common-mode voltage swings caused by switching noise in inverters and DC-DC converters. It is also used in automotive DC bus current monitoring for power distribution networks, regenerative braking current control, and on-board charger current feedback loops requiring AEC-Q100 qualified, precision, compact current sense solutions.

Frequently Asked Questions
What is the PINA293A1QDBVRQ1 and what makes it suited for automotive use?
The PINA293A1QDBVRQ1 is an automotive-grade high-voltage unidirectional current sense amplifier from Texas Instruments. It is AEC-Q100 qualified (indicated by the Q1 suffix), meaning it has been tested and qualified to automotive reliability standards for use in under-hood and other harsh automotive environments across the full automotive temperature range, making it suitable for safety-critical current monitoring in EV and hybrid vehicle powertrains.
What is the maximum common-mode voltage of the PINA293A1QDBVRQ1?
The PINA293A1QDBVRQ1 supports a maximum common-mode voltage of 110V, allowing it to measure current via a shunt resistor on a high-side rail up to 110V above ground. This is essential for automotive 48V mild-hybrid systems, battery pack monitoring, and EV traction inverter current sensing where the measurement node floats well above the chassis ground reference.
What is the CMRR specification of the PINA293A1QDBVRQ1?
The PINA293A1QDBVRQ1 achieves a minimum common-mode rejection ratio (CMRR) of 140 dB with a typical value of 160 dB. This exceptionally high CMRR is critical for accurate current measurement in noisy automotive switching environments, as it ensures that large common-mode voltage transients caused by PWM motor drives and DC-DC converters do not corrupt the small differential shunt voltage signal being amplified.
What package does the PINA293A1QDBVRQ1 use?
The PINA293A1QDBVRQ1 is housed in a 5-pin SOT-23 (DBV) surface-mount package, one of the most compact standard IC packages available. This tiny footprint is ideal for space-constrained automotive ECUs, battery management modules, and motor controller PCBs where multiple current sensing points are required and PCB area per function is strictly limited.
What is the input offset voltage of the PINA293A1QDBVRQ1 and why does it matter?
The PINA293A1QDBVRQ1 has a maximum input offset voltage of 200 µV. In current sensing applications, offset voltage translates directly to a current measurement error: with a 1 mΩ shunt resistor and 200 µV offset, the error is 200mA. The tight 200 µV specification ensures sufficient current measurement accuracy for automotive battery state-of-charge estimation, motor torque control, and overcurrent fault detection at low current levels where precision is most critical.
