AMC1300BQDWVRQ1

The AMC1300BQDWVRQ1 stands out as a precision, isolated amplifier that sets new standards in performance, safety, and reliability. With its reinforced galvanic isolation, outstanding DC accuracy, and simplified system-level design, it offers unparalleled benefits for various applications in the automotive and power control industries. As technology continues to evolve, the AMC1300B-Q1 remains at the forefront, driving innovation and efficiency in modern electronics and automotive systems.

• Shunt-resistor-based current sensing in:

– HEV/EV charging piles

– HEV/EV onboard chargers (OBC)

– HEV/EV DC/DC converters

– HEV/EV traction inverters

The AMC1300B-Q1 is a precision, isolated amplifier with an output separated from the input circuitry by an isolation barrier that is highly resistant to magnetic interference. This barrier is certified to provide reinforced galvanic isolation of up to 5 kVRMS according to DIN EN IEC 60747-17 (VDE 0884-17) and UL1577, and supports a working voltage of up to 1.5 kVRMS.

The isolation barrier separates parts of the system that operate on different common-mode voltage levels and protects the low-voltage side from hazardous voltages and damage.

The input of the AMC1300B-Q1 is optimized for direct connection to a low-impedance shunt resistor or other low-impedance voltage source with low signal levels. The excellent DC accuracy and low temperature drift supports accurate current control in PFC stages, DC/DC converters, traction inverters, and OBCs over the full automotive temperature range from –40°C to +125°C.

The integrated missing-shunt and missing high-side supply detection features simplify system-level design and diagnostics.
