Description

The is an isolation amplifier that provides accurate, electrically isolated and amplified representations of voltage and current. When used with a shunt resistor to monitor the motor phase current in a high speed motor drive, the device will offer superior reliability compared with the traditional solutions such as current transformers and Hall-effect sensors. The HCPL-7850/7851

consists of a sigma-delta analogto-digital converter optically coupled to a digital-to-analog converter in a hermetically sealed package. The products are capable of operation and storage over the full military temperature range and can be purchased as either commercial product or with full MIL-PRF-38534 Class H testing or from the appropriate DSCC drawing. All devices are manufactured and tested a MIL-PRF-38534 certified line and are included in the DSCC Qualified Manufacturers List, QML-38534 for Hybrid Microcircuits.

0.1 F bypass capacitor must be connected between pins 1 and 4 and between pins 5 and 8. CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to prevent damage and/or degradation which may be induced by ESD.

Superior performance in design critical specifications such as common-mode rejection, offset voltage, nonlinearity, and operating temperature make the HCPL-7850/7851 an excellent choice for designing reliable products such as motor controllers and inverters.

Common-mode rejection of 8 kV/�s makes the HCPL-7850/ 7851 suitable for noisy electrical environments such as those generated by the high switching rates of power IGBTs.

Low offset voltage together with a low offset voltage temperature coefficient permits accurate use of auto-calibration techniques. Gain tolerance of 5% with 0.1% nonlinearity further provide the performance necessary for accurate feedback and control.
