1 MAX78 Evaluation Kit Evaluates: MAX78 General Description The MAX78 evaluation kit (EV kit) is a fully assembled and tested circuit for evaluating the MAX78 USB Type-C charger. Refer to the MAX78 IC data sheet for detailed information regarding the operation and features of the devices. For additional information, please refer to the MAX78 user guide. Features RoHS Compliant Proven PCB Layout Full Assembled and Tested IC Serial Interface Ordering Information appears at end of data sheet. 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, 0.05in posts. Settings in Table marked with an asterisk ( * ) indicate default placements. Digital Inputs and Outputs The bias for the logic inputs and open-drain indicators is provided from the VMC pin of J connector. Install jumper between - pins of JU5 to use VMC for the supply. The CDIR, OK, and INT open-drain outputs use supply for their respective pullup voltages. Jumpers JU, JU, JU connect the indicator LED, LED, and LED to these open-drain flags. Based on the Type-C state machine output, BVCEN pushpull output controls the external load switch Q. When BVCEN is high, Q connects VCONN to the external supply source applied at TP9. FLTIN and FSUS are digital inputs set by JU7 and JU8. FLTIN is the charger fault input. If pulled low, FLTIN forces the charger into a fault state. FSUS is the force suspend input. If pulled high, it forces the input current limit to 0A ; Rev 0; 9/7

3 MAX78 Evaluation Kit Evaluates: MAX78 USB Interface The MAX78 provides an integrated USB.0 full-speed interface (Mbps). This interface is accessed through the USB Type-C connector J and USB Type-A connector J_USB_A. VBUS_C of J is also a power source for U. I/O Interface Connector The EV kit allows accessing the IC interface of the MAX78 through the J5 PMOD connector. Please refer to Table for the connectors pin description. Table.
