The EVM enables a user to evaluate ISOW6441 device thoroughly before incorporating the device into a design. To facilitate the EVM to be powered from various power sources including regulated power supplies, standard DC adapters and batteries, EVM includes two adjustable output LDOs (TPS7A4701) that are connected to VDD and VDDL pins (VDDL only for 'V' variant) where for ISOW6441, only VDD is connected by default on the EVM. This allows the LDO inputs to be connected to a wider range of supply voltages and the optimum voltage for normal operation of the EVM is between 9V to 12V. The EVM also includes an onboard oscillator (LTC6908-1) that can be connected to the inputs of ISOW6441 through 0Ω resistors. The oscillator helps to provide a quick test signal to verify device operation. The EVM can be configured to operate in various power supply voltages and test configurations the details of which are provided in following sections.
