2.3 EVM Setup and Operation

This section describes the typical test setup and operation of the EVM for evaluating the device. Figure 3-3 shows a typical test configuration for operating the ISO7741TADWEVM using a single power supply to power VCC1 of the device. VCC2 of device is powered by the isolated power supply generated by the push-pull isolated power supply. Push-pull isolated power supply consists of the integrated push-pull transformer driver, the external push-pull transformer, rectifier diodes, filtering capacitors and the optional LDO TPS7A2601. Jumper J4 allows to power VCC2 of ISO7741TA in one of two ways, either directly from the push-pull power supply output (when pins 1 and 2 shorted) or through the regulated LDO output (when pins 2 and 3 shorted).
