Frequently Asked Questions

What common-mode voltage range does the PINA293A2QDBVRQ1 support and which automotive bus architectures benefit from this?

The PINA293A2QDBVRQ1 supports common-mode input voltages up to 110V, covering 12V, 24V, and 48V automotive bus rails plus higher-voltage EV traction battery stacks. This 110V range allows high-side shunt measurement directly on main battery rails in mild hybrid vehicles, eliminating the need for voltage dividers or isolation in motor control ECUs.

How precise is the current measurement using PINA293A2QDBVRQ1 given its input offset voltage specification?

The PINA293A2QDBVRQ1 specifies a maximum input offset voltage of 200 µV, which translates to a measurement error of only 2 mA with a 100 mΩ shunt resistor. This precision is critical for battery state-of-charge algorithms and overcurrent detection in automotive BMS designs where measurement inaccuracy directly impacts vehicle range estimation and safety thresholds.

What CMRR does the PINA293A2QDBVRQ1 achieve and why does this matter in automotive EMI environments?

The PINA293A2QDBVRQ1 delivers 160 dB typical and 140 dB minimum CMRR, rejecting common-mode interference by a factor exceeding 10 million. In automotive environments with high-frequency switching noise from inverters and DC-DC converters operating at 10 kHz to 100 kHz, this CMRR ensures that the differential current signal is accurately extracted from large common-mode disturbances.

Is the PINA293A2QDBVRQ1 suitable for high-temperature automotive powertrain locations and what qualification does it carry?

The PINA293A2QDBVRQ1 is AEC-Q100 qualified for automotive reliability and operates over the full -40°C to +125°C junction temperature range. This qualification makes it appropriate for under-hood powertrain locations, motor controller housings, and battery management modules in hybrid and electric vehicles where sustained high-temperature operation is required.
