MAX1493XSEVKIT#

MAX1493X Evaluation Kit General Description The MAX1493X evaluation kit (EV kit) demonstrates the functionality of the MAX1493X 4-channel, unidirectional, digital isolators in a 16-pin, SOIC surface-mount package. The functionality and performance of the QSOP versions (MAX1413x) can be tested indirectly by using this EVkit populated with any of the equivalent narrow or wide SOIC (MAX1493x) 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 +5V. Evaluates: MAX14130, MAX14131, MAX14930, MAX14931, MAX14932, MAX14934, MAX14935, MAX14936 Features ●● Ease of Use • Easy Powering Through Micro-USB or Test Points • SMA Connectors to Connect to External Equipment ●● Guaranteed Up to 5kVRMS Isolation (for the Wide-Body SOIC Version) • Also Evaluates the 2.75KVRMS Versions. Ordering Information appears at end of data sheet.

The user can install the desired flavor of the MAX1493X family of unidirectional isolators. Once installed, follow the steps below to verify board operation: 1) Connect the DC power supplies between the MAX1493X EV kit’s VDDA/VDDB and GNDA/GNDB test points. 2) Turn on the DC power supplies and set to 5V, then enable the power-supply output. Note: It is also possible to power the MAX1493X 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). 3) Connect any signal to the SMA connectors or test points and observe the isolated signal on the other side using an oscilloscope. Power on the MAX1493X EV kit is derived from two +5V sources. Connect external supplies to the +5V and GNDA test points, or connect a micro-B USB cable to the on-board PA/PB connectors to provide the 5V. Both options have a reverse-current protection diode. The MAX1493X 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 1 is a simplified schematic showing the connections for evaluating the MAX1493X in a simple microprocessor interface. The MAX1493X level-shifts the signals and transmits them across the isolation barrier.

MAX1493X EV Kit Component Placement Guide (Top Silkscreen) Figure 3. MAX1493X EV Kit PCB Layout (Top Layer) Each input and output has an unpopulated resistor and capacitor to GND_ to allow terminating based on customer requirements. 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 VDDA/VDDB, respectively. Figure 4.
