Part Details for MAX77 by Maxim Integrated Products

The MAXREFDES1214 is a portable USB charger that uses a lithium-ion (Li+) battery to charge a USB device from a USB Standard-A connector. The battery can be charged through Micro-USB. The MAXREFDES1214 is compliant with USB Battery Charger (BC) revision 1.2 on both USB ports. It has dynamic charger detection to automatically set the maximum charge current allowed to the battery based on the source’s capability. It also features a USB adapter emulator that supports Apple® 1A charging in addition to devices that are compliant with USB BC 1.2. For added flexibility, an I2C bus provides fault monitoring and shutdown capability for the buckboost regulator.<p>Key Features<p>Battery Charger Input Current up to 1A<p>USB Standard-A Output Current up to 1.5A<p>4400mAh Li+ Battery<p>Thermal and Overcurrent Protection on the USB Standard-A Output<p>I2C Headers for Flexible Logic Levels from 1.8V to 5.0V<p>Orange LED to Indicate if the Battery Is Charging<p>No External Reverse Blocking Diode Required Between Battery and Charger

Size, cost and complexity are some issues facing Power Electronics Engineers when it comes to designing a power solution for high power FPGAs. The Mulltiphase Controller, Multiphase Powerstage and MAX77812 are just some of the Maxim ICs which eliminate these issues when completing a high power, multiple output design. The combination of the highly integrated Multiphase Controller with the Multiphase Powerstage ICs eliminates the need for many external components when designing for a high current rail. While our highly efficient MAX77812 PMIC easily manages the lower power rail requirements.<p>In this design a single 12V input supplies a circuit which outputs 6 separate rails ranging from 500mW to 130W.<p>The design is specified to meet the XILINX Versal ACAP AI Core Series UC1/3 requirements. The design layout is also optimized for the Versal ACAP IC.<p>Power Solutions for Xilinx Versal, Artix-7, Spartan-7, and Zynq US+ MPSoC FPGAs ›

The MAXREFDES96# is an Arduino Uno R3-compatible board that provides battery charge, boost, and data-logging capabilities. The board can be operated tethered to a power supply or computer to charge a battery and operate untethered to use the battery to power the Arduino board. An SD card interface is provided to enable data logging up to 32GB of data. Status and battery state of charge (SOC) is displayed on three LEDs. An Arduino-compatible display can be added for more detailed data display.<p>Design files, firmware, and software can be found on the Design Resources tab tab. The board is also available for purchase.
