Evaluates: MAX14591 MAX14591 Evaluation Kit General Description Quick Start The MAX14591 evaluation kit (EV kit) is a fully assembled Required Equipment and tested circuit board that demonstrates the function- MAX14591 EV kit ality of the MAX14591 high-speed, open-drain capable Digital voltmeter (DVM) logic-level translator in both the 8-bump WLP and 8-pin TDFN packages. Only the TDFN package device is USB power source or another 5V external power supply installed in this EV kit. The EV kit enables direct evalua- Oscilloscope and at least one scope probe tion of the device by multiple jumper-selectable methods. The highly configurable PCB allows the user to evaluate Procedure each package separately or both at once. Input power to The EV kit is fully assembled and tested. Follow the steps the EV kit is provided by a micro-USB, type-B connector below to verify board operation and begin evaluation: or an external 5V power supply. On-board LDO regulators 1) If using a USB bus to power the board, connect the provide the appropriate voltage for each component, and included micro-USB cable between the micro-USB, potentiometers allow the user to adjust the power supply type-B connector (J1) and the USB power source, for either side of the level translator independently. such as a computer or dedicated USB charging port, and install a shunt on jumper JP4 shorting pins 1-2. Features and Benefits 2) If using an external power source to power the board, Proven PCB Layout connect the external power supply at the VBUS test Decrease Evaluation Time point (TP26) and install a shunt on jumper JP4 short- Fully Assembled and Tested ing pins 2-3. On-Board Adjustable Oscillators 3) Connect the DVM between GND (TP6) and V CC Evaluate Without External Function Generator (TP24). Adjust the first potentiometer (POT1) until the Jumper-Selectable Open-Drain and Push-Pull Buffers desired voltage for V appears on the DVM by turn- CC Enable Simple Evaluation ing the screw on the potentiometer to the right or to the left. 4) Connect the DVM between GND (TP6) and V (TP25). L Ordering Information appears at end of data sheet. Adjust the second potentiometer (POT2) until the desired voltage for V appears on the DVM by turning L the screw on the potentiometer to the right or to the left. Note that V should be lower than V . L CC 5) Connect the jumpers according to Table 1 to verify U2 (MAX14591ETA+) operation. 6) Connect the oscilloscope probe to TP19 I/OVCC2 and TP21 I/OVCC1 to observe the translated voltage of the input signal. 19-6828 Rev 1 3/19Evaluates: MAX14591 MAX14591 Evaluation Kit Table 1. Jumper Configuration (JP1JP7, JP9JP15, JP17JP25) SHUNT JUMPER DESCRIPTION POSITION 1-2* Pullup resistor connect for I/OVL2 of U2. Connects a 1k pullup resistor between V and I/OVL2. L JP1 Pullup resistor disconnect for I/OVL2 of U2. Disconnects the 1k pullup resistor between V and L Not installed I/OVL2. Connects open-drain buffer to driving signal bus for channel I/OVL1. The open-drain buffer is driven 1-2* by the output of DS1090-16 (U4). The frequency of the signal is adjustable using POT3. JP2 1-3 Connects external source connected at TP9 to driving signal bus for channel I/OVL1. Connects push-pull buffer to driving signal bus for channel I/OVL1. The push-pull buffer is driven by 1-4 the output of DS1090-1 (U5). The frequency of the signal is adjustable using POT4. Pullup resistor connect for I/OVCC2 of U2. Connects a 1k pullup resistor between V and I/ CC 1-2* OVCC2. JP3 Pullup resistor disconnect for I/OVCC2 of U2.
