MAX14434–MAX14436 Evaluation Kit General Description The MAX14434–MAX14436 evaluation kit (EV kit) provides a proven design to evaluate the MAX14434– MAX14436 four-channel unidirectional digital isolators. Three types of evaluation boards are available to support different channel direction configurations of the MAX14434–MAX14436 family. All evaluation boards support the wide-body 16-pin SOIC package type. See Table 1 for EV kit options. The EV kit should be powered from two independent isolated power supplies with nominal output voltage in range from 1.71V to 5.5V. For evaluating the electrical parameters of the device without any isolation between the two sides, a single power supply can also be used. The MAX14434FWEVKIT# comes populated with MAX14434FAWE+, but can also be used to evaluate the following digital isolators: MAX14434BAWE+, MAX14434CAWE+, MAX14434EAWE+. The MAX14435FWEVKIT# comes populated with the MAX14435FAWE+, but can also be used to evaluate the following digital isolators: MAX14435RAWE+, MAX14435SAWE+, MAX14435UAWE+, and MAX14435VAWE+. Evaluates: MAX14434–MAX14436 Features ●● Broad Range of Data Transfer Rates (from DC to 200Mbps) ●● Four Unidirectional Channels with 3 Different Channel Direction Configurations ●● SMA Connectors for Easy Connection to External Equipment ●● Wide Power Supply Voltage Range from 1.71V to 5.5V ●● Guaranteed Up to 5kVRMS Isolation for the WideBody SOIC Package for 60s Ordering Information appears at end of data sheet. The MAX14436WEVKIT# comes populated with the MAX14436FAWE+, but can also be used to evaluate the following digital isolators: MAX14436BAWE+, MAX14436CAWE+, MAX14436EAWE+. Table 1.

Required Equipment ●● MAX14434FW, MAX14435FW, or MAX14436FW ●● Two DC power supplies with output range of 1.71V to 5.5V 2) Connect one DC power supply between the EV kit’s TP_VDDA and TP_GNDA test points; connect the other DC power supply between TP_VDDB and TP_ GNDB test points. 3) Set both DC power supply outputs between 1.71V and 5.5V, and then enable the power supply outputs. Note: It is also possible to power the EV kits from a single power supply to test electrical parameters but this invalidates the digital isolation of the IC. 4) Connect the signal/function generator to an input SMA connector or test point of side A and observe the isolated signal on the corresponding side B output, using an oscilloscope. ●● Signal/function generator ●● Oscilloscope Procedure The MAX14434FW, MAX14435FW, and MAX14436FW EV kits are fully assembled and ready for evaluation. For manual verification follow the steps below to verify board functionality: 1) Verify jumper settings. See Table 2 for all shunt positions. • J1 and J2 are closed. Table 2.

External Power Supplies Power to the MAX14434FW, MAX14435FW, and MAX14436FW EV kits is derived from two external sources which can both be between +1.71V and +5.5V. Connect one source between the VDDA and GNDA test points, and the other source between the VDDB and GNDB test points. Each supply can be set independently and can be present over the entire range from 1.71V to 5.5V, regardless of the level or presence of the other supply. The MAX14434MAX14436 level-shift the data, transmitting them across the isolation barrier. Four SMA connectors on each side of the board allow easy connections to signal generator(s) and oscilloscope. A typical test setup is shown in Figure 2. Decoupling Capacitors Each power supply is decoupled with a 10µF ceramic capacitor in parallel with a 0.1µF ceramic capacitor, which are placed close to the U1 VDDA and VDDB pin. Each input and output has an unpopulated 0603 SMT resistor (RA1-RA4, RB1-RB4) and an unpopulated 0603 SMT capacitor (CA1–CA4, CB1–CB4) to GND_ to allow termination based on customer requirements. Shunt Positions Jumpers J1 and J2 are installed between the external power supplies and U1 power supply pins to allow supply current measurement. Uninstall the J1 and J2 shunts and connect current meters on both side A and side B to measure the MAX14434-MAX14436 supply current. Jumper ENA is provided to enable or disable the side A of the isolator channels. To enable the devices with activehigh enable pin on the side A (MAX1443_B/C/E/F), connect the ENA shunt to VDDA. To enable the devices with active-low enable pin on the side A (MAX14435R/S/U/V), connect the ENA shunt to GNDA. The side A outputs are high-impedance when disabled. Jumper ENB is provided to enable or disable the side B of the isolator channels. Connect the ENB shunt to VDDB to enable the side B channels, or connect to GNDB to disable the side B channels. The side B outputs are high-impedance when disabled. See Table 2 for all shunt positions.
