General Description The MAX7 evaluation kit (EV kit) is a fully assembled and tested circuit for evaluating the MAX7/ MAX77 charger detectors with a linear battery charger and a smart power selector. Refer to the MAX7 IC data sheet for detailed information regarding the operation and features of the devices. The EV kit comes standard with the MAX7 installed, but can also be used to evaluate the MAX77 by replacing the MAX7 (U) with the MAX77. Request a free sample of the MAX77 when ordering the EV kit. Benefits and Features RoHS Compliant Proven PCB Layout Full Assembled and Tested IC Serial Interface Ordering Information appears at end of data sheet. Quick Start Required Equipment Digital Multimeter (DMM) One USB-A to micro-b cable Windows XP, Windows Vista, Windows 7, or Windows 0 PC with one available USB port Optional: USB Mouse Optional: IC Controller Device Procedure The EV kit is fully assembled and tested. Follow the steps below to verify basic board operation: Caution: Do not turn on the power supply and external devices until all connections are completed. ) Verify that all jumpers are in their default positions, as shown in Table. Windows, Windows Vista, and Windows XP are registered trademarks and registered service marks of Microsoft Corporation ) Use the USB-A to micro-b cable to connect J to the PC. ) Measure the voltage on test point. Confirm that it equals approximately.v. ) Measure the voltage on test point. Confirm that it equals approximately.v. ) Measure the voltage on SFOUT test point. Confirm that it equals approximately V. ) Optional: Connect the USB mouse to J. Confirm that the mouse can control the mouse cursor on the PC after enumeration. 7) Optional: To configure the device s registers, connect the IC controller device to GND, (J pin ) and (J pin ), and use it to program the registers. 8) The EV kit is ready for additional evaluation. Detailed Description of Hardware Jumper Descriptions Table details the functions of the configurable jumper headers on the EV kit board. The headers are standard 0.in spacing, 0.0in posts. Table.

Install jumper JU to use VMC for the supply. The UOK, UOK, INT, CTYP, open-drain outputs use supply for their respective pullup voltages. Jumpers JU JU connect the indicator LEDs D D to these open-drain flags. LED pin is another open-drain output, the status of which is reflected by indicator D when JU is installed. UOK/EXT pin is preconfigured by factory as either UOK or EXT. EXT is a push-pull output used to control the external pmos load switch Q. When charger is not present, EXT is high and Q connects to. Connect JU accordingly based on which function UOK/EXT is preconfigured to. and are digital inputs set by JU and JU. determines if the current limit is fixed at 00mA or controlled by IC settings (IBusLim, ILimSet, IBusDetSw bits);, if pulled high, forces the input current limit to 0A USB Inferface The MAX7 provides an integrated USB.0 full-speed interface (Mbps). This interface is accessed through the Micro-USB type-b connector, J and type-a connector J. VBUS of J is also the power source for the U. I/O Interface Connector The EV kit allows accessing the digital I/O of the MAX7 individually through three different interface connectors, J, J, and J.
