EV Kit is Ready for Factory IC Option with Customer The MAX25430A provides CC signal passthrough protec- Cable Shield Short-to-Battery Protection tion for the Cypress CCG3PA USB-PD controller. Proven PCB Layout The integrated USB Type-C protection switches provide Fully Assembled and Tested automotive system-level ESD and 24V short-circuit pro- tection for D+, D-, CC1, CC2, and CC lines when used as VCONN supply. The device also supports legacy USB 2.0 charging modes including BC1.2, Apple 2.4A, Apple CarPlay, Apple MFi and USB On-The-Go (OTG). The register set can be reviewed using the Maxim 2 Feather Board I C to USB adapter, and the MAX2543x Graphical User Interface (GUI). Please contact the factory for more details. The MAX25430 offers a factory option that includes intel - ligent detection and protection to avoid high short-circuit currents flowing from the car battery through the cable shield to ground during fault events, preventing car mod- ule damage. To evaluate, refer to the Ordering Information table in the MAX25430 datasheet and order the G-suffix sample from the factory. Once received, replace on the EV Kit and unsolder the bypass short around MOSFET (Q6). Ordering Information appears at end of data sheet. 319-100582 Rev 1 8/20Evaluates: MAX25430 MAX25430A Evaluation Kit Quick Start The following procedure demonstrates the MAX25430As charging functionality. The register set and GUI are described in the detailed description section. EV Kit Content MAX25430 EVKIT P3 00 board is referred to as MAX25430A EV Kit Board MAXPD CY01 APPS A board is referred to as PD Controller Board MAXPD FTHR APPS B board is referred to as Feather Board 6ft USB Type-C 5A Cable Required Equipment MAX25430A EV Kit Board PD Controller Board 6ft USB Type-C Cable 14V/10A DC Power Supply or car battery (V ) BAT Digital voltmeter (DVM) Device with Type-C port for charging Initial Setup The EV kit is fully assembled and tested. Follow the steps below to set up the board for evaluation. 1) Verify the jumper settings on the MAX25430A EV Kit Board match the settings in the tables below. MAX25430A EV KIT BOARD JUMPER SETTINGS OPEN, NO JUMPER SHORT PINS 1 AND 2 SHORT PINS 2 AND 3 J2, J8, J9, J13, J15 J6, J7, J12, J14, J34 J1 2 2) Verify the I C address switch (SW1) match the settings in the tables and images in the quick-start guide. 2 I C ADDRESS SWITCH SETTINGS SWITCH 1 SWITCH 2 SWITCH 3 SWITCH 4 ON OFF OFF OFF 3) Verify the jumper settings on the PD Controller Board match the settings in the tables PD CONTROLLER BOARD JUMPER SETTINGS OPEN, NO JUMPER SHORT PINS 1 AND 2 SHORT PINS 2 AND 3 J5, J6, J7, J11 J8, J9, J10 J2 4) Push the two boards together at J3 (40-pin header) as shown in the Initial EV kit setup below, Figure 1. 5) Set the V power supply to 14V output, 5A current limit. Turn the output off. Connect the negative lead to the BAT GND2 test loop on MAX25430A EV Kit Board. Connect positive lead to VBAT FLT test loop on the MAX25430A EV Kit Board. 6) Connect the DMM positive lead to the HVBUS test loop on the MAX25430A EV Kit Board and connect the negative lead to the GND4 test loop on the MAX25430A EV Kit Board. Set for the DMM for voltage measurement. 7) Turn the V power supply output on. BAT 8) Verify there is 0V on DMM. 9) Connect a USB Type-C device such as a laptop or mobile phone that can consume power over a Type-C port to J37 of the MAX25430A EV Kit Board. 10) Measure the V to ensure 5V, 9V, 15V, or 20V is being applied to the device.
