1 MAX9X Evaluation Kit Evaluates: MAX0, MAX, MAX90, MAX9, MAX9, MAX9, MAX9, MAX9 General Description The MAX9X evaluation kit (EV kit) demonstrates the functionality of the MAX9X -channel, unidirectional, digital isolators in a -pin, SOIC surface-mount package. The functionality and performance of the QSOP versions (MAXx) can be tested indirectly by using this EVkit populated with any of the equivalent narrow or wide SOIC (MAX9x) devices. The functionality and electrical performance of the QSOP versions are identical to their corresponding SOIC versions. The EV kit features two independent isolated power supplies independently adjustable to +V. Features Ease of Use Easy Powering Through Micro-USB or Test Points SMA Connectors to Connect to External Equipment Guaranteed Up to kv RMS Isolation (for the Wide-Body SOIC Version) Also Evaluates the.kv RMS Versions.

2 MAX9X Evaluation Kit Quick Start Required Equipment MAX9X EV kit MAX9X device separated sampled Two V DC power supplies or USB cables with a micro-b connector Signal/function generator Oscilloscope Procedure The MAX9X EV kit has everything except the DUT installed. The user can install the desired flavor of the MAX9X family of unidirectional isolators. Once installed, follow the steps below to verify board operation: ) Connect the DC power supplies between the MAX9X EV kit s / and / test points. ) Turn on the DC power supplies and set to V, then enable the power-supply output. Note: It is also possible to power the MAX9X EV kit with standard USB ports. To do so, connect the micro-b-end of the USB cables into PA/PB on the board. Connect the A-end of the USB cable into the USB ports. Please ensure that only one type of supply is used on either side (USB or DC power supply). ) Connect any signal to the SMA connectors or test points and observe the isolated signal on the other side using an oscilloscope. Evaluates: MAX0, MAX, MAX90, MAX9, MAX9, MAX9, MAX9, MAX9 Detailed Description of Hardware (or Software) The MAX9X EV kit is powered from two +V supplies, as described below. External Power Supplies Power on the MAX9X EV kit is derived from two +V sources. Connect external supplies to the +V and test points, or connect a micro-b USB cable to the on-board PA/PB connectors to provide the V. Both options have a reverse-current protection diode. The MAX9X level-shifts the data and control signals, transmitting them across the isolation barrier. Each supply is set independently and can be present over the entire specified range of the device, regardless of the level or presence of the other supply. Figure is a simplified schematic showing the connections for evaluating the MAX9X in a simple microprocessor interface. The MAX9X level-shifts the signals and transmits them across the isolation barrier.

3 MAX9X Evaluation Kit Termination Each input and output has an unpopulated resistor and capacitor to GND_ to allow terminating based on customer requirements. Evaluates: MAX0, MAX, MAX90, MAX9, MAX9, MAX9, MAX9, MAX9 Jumpers Two jumpers (ENA/ENB) are provided to enable either side of the isolation barrier. These are active-high signals. To enable each side, connect to /, respectively. Figure. MAX9X EV Kit Component Placement Guide (Top Silkscreen) Figure. MAX9X EV Kit PCB Layout (Top Layer) Figure.
