Click here for production status of specific part numbers. Evaluates: MAX14748 MAX14748 Evaluation Kit Procedure General Description The EV kit is fully assembled and tested. Follow the steps The MAX14748 evaluation kit (EV kit) is a fully assembled below to verify board operation: and tested circuit for evaluating the MAX14748 USB Type-C charger. Refer to the MAX14748 IC data sheet for 1) Visit Evaluates: MAX14748 MAX14748 Evaluation Kit The CDIR, SYSOK, and INT open-drain outputs use VIO Detailed Description of Hardware supply for their respective pullup voltages. Jumpers JU1, Jumper Descriptions JU3, JU4 connect the indicator LED1, LED3, and LED4 to Table 1 details the functions of the configurable jumper these open-drain flags. headers on the EV kit board. The headers are standard Based on the Type-C state machine output, BVCEN push- 0.1in spacing, 0.025in posts. Settings in Table 1 marked pull output controls the external load switch Q2. When with an asterisk (*) indicate default placements. BVCEN is high, Q2 connects VCONN to the external sup- ply source applied at TP19. Digital Inputs and Outputs The bias for the logic inputs and open-drain indicators is FLTIN and FSUS are digital inputs set by JU7 and JU8. FLTIN is the charger fault input. If pulled low, FLTIN forces provided from the VMC pin of J4 connector. Install jumper between 2-3 pins of JU5 to use VMC for the VIO supply. the charger into a fault state. FSUS is the force suspend input. If pulled high, it forces the input current limit to 0A. Table 1.
