3-V Operation on Low-Side • Certified Galvanic Isolation: – UL1577 and VDE V 0884-10 Approved – Isolation Voltage: 4250 VPEAK – Working Voltage: 1200 VPEAK – Transient Immunity: 10 kV/µs (min) • Typical 10-Year Lifespan at Rated Working Voltage (see Application Report, SLLA197) 2 Applications • Isolated Shunt-Resistor-Based Current or Voltage Sensing in: – Traction Inverters – On-Board Chargers – DC-DC Converters – Battery Management Systems 3 Description The AMC1200-Q1 is a precision isolation amplifier with the output separated from the input circuitry by a silicon dioxide (SiO2) barrier that is highly resistant to magnetic interference.
This barrier is certified to provide galvanic isolation of up to 4250 VPEAK according to UL1577 and VDE V 0884-10.
Used in conjunction with isolated power supplies, this device prevents noise currents on a high common-mode voltage line from entering the local ground and interfering with or damaging sensitive circuitry.
The input of the AMC1200-Q1 is optimized for direct connection to shunt resistors or other low-voltage level signal sources.
The performance of the device supports accurate current control, resulting in systemlevel power saving and (especiall...
