What are the key features of PINA290A2QDCKRQ1?
- Ultra-wide 2.7 V to 110 V common-mode voltage range covering 12 V, 24 V, 48 V, and 110 V bus rail architectures
- AEC-Q100 Grade 1 automotive qualification for -40°C to 125°C operation in harsh environments
- 800 kHz bandwidth in a 5-pin SC-70 package enabling high-speed current monitoring in space-constrained designs
What is PINA290A2QDCKRQ1 used for?
The PINA290A2QDCKRQ1 is designed for automotive battery-management systems and motor-drive controllers where precise high-side current sensing across wide common-mode swings up to 110 V is required. Its AEC-Q100 Grade 1 rating makes it suitable for ADAS, EV powertrain, and industrial motor drives operating over a -40°C to 125°C temperature range. The 800 kHz bandwidth supports fast overcurrent detection in DC-DC converters and power-distribution units.
