Automotive Isolated Amplifier for Current Sensing
The CA-IS1300B25G-Q1 devices are high-precision isolated amplifiers and optimized for shunt-resistor-based current sensing. Low offset and gain error and drift guarantee that measuring accuracy is maintained over the entire operating temperature range.
The CA-IS1300B25G-Q1 devices utilize silicon oxide (SiO2) isolation barriers and support up to 5-kVRMS galvanic isolation per UL 1577. This technology separates high- and low-voltage domain to protect lower-voltage parts from damage and provides low emissions as well as strong antiinterference capability from magnetic changes. The high common-mode transient immunity (CMTI) means that the CA-IS1300B25G-Q1 devices transmit correct signals through isolation barriers and are suitable for automotive motor controls and drives which require high-voltage and highpower switching. The internal input common-mode overvoltage and missing high-side supply voltage detection functions contribute to fault diagnostics and system safety.
The CA-IS1300B25G-Q1 devices are packaged in wide body, 8-pin SOIC packages and specified over the automotive temperature range of –40°C to 125°C.
