Analog Devices Inc./Maxim Integrated MAX25460EVKIT#

Overview

MAX25460EVKIT# from Analog Devices is a fully assembled and tested evaluation kit for the MAX25460 automotive USB Type-A controller IC, featuring 1GHz BW USB 2.0 D+/D- protection switches, a 2.2MHz step-down DC-DC converter delivering up to 1.5A continuous output, integrated high-side current sensing, and automatic USB voltage adjustment for cable drop compensation in automotive applications.

For engineers reviewing the MAX25460EVKIT# datasheet, MAX25460EVKIT# pinout, MAX25460EVKIT# application, or MAX25460EVKIT# equivalent, this board enables rapid validation of USB BC1.2 CDP charging, spread-spectrum EMI mitigation, adjustable buck current limit, cable compensation gain tuning (up to 474mΩ), and fault-interrupt diagnostics via I2C GUI interface.

Technical Context

The MAX25460EVKIT# implements the MAX25460ATGA/V+ variant operating at 2.2MHz with FPWM or skip-mode control selectable via SYNC pin configuration. It integrates a 28V-input buck regulator with 40V load-dump transient tolerance, USB 2.0 high-speed data switches (D+/D−), and programmable charge detection modes (SDP/CDP) compliant with USB-IF BC1.2.

Board-level functionality includes on-board MAX32625PICO microcontroller for USB-to-I2C bridging, configurable hardware switches (SW1) for HVEN/ENBUCK/SYNC/DATA_MODE control, test points for VBAT_FLT, GND_1, USB_5V, and FAULT/INT signal monitoring, and pre-populated 0Ω resistors replacing LC tuning networks for simplified high-speed data path evaluation.

FAQ

What does the MAX25460EVKIT# evaluate and how is it configured?

The MAX25460EVKIT# evaluates the MAX25460ATGA/V+ automotive USB Type-A controller, pre-configured for 2.2MHz operation with spread spectrum enabled, Auto_CDP charge detection, and 0Ω resistors in place of LC tuning networks. It ships fully assembled with onboard Pico module, USB-A receptacle (J3), plug (J2), and test loops for VBAT_FLT and GND_1.

Does the MAX25460EVKIT# support USB BC1.2 CDP charging mode verification?

Yes, the MAX25460EVKIT# supports full BC1.2 CDP charging validation: set Charge Detection to Auto_CDP in the GUI, connect a CDP-compatible smartphone, and verify both host recognition and charging current via R1 voltage drop measurement. The MAX25460EVKIT# implements all required D+/D− handshake logic and voltage regulation per USB-IF specification.

How is cable compensation validated using the MAX25460EVKIT#?

Cable compensation is validated by connecting a 2m USB-A extension cable to J3, attaching a Type-A plug, measuring far-end VBUS (~5.15V), then adjusting Cable Comp Gain in the GUI while loading the far end with an electronic load or resistor bank until regulated VBUS is maintained - confirming the MAX25460EVKIT#'s ability to compensate for up to 474mΩ cable resistance.

What interfaces and controls are accessible on the MAX25460EVKIT#?

The MAX25460EVKIT# provides J1 (12-pin header) for IN, SYNC, DATA_MODE, HVEN, ENBUCK, FAULT, INT, BIAS, SCL, SDA, and GND signals; SW1 dip switch for hardware pin state selection; test loops for VBAT_FLT, GND_1, USB_5V, HOST_VBUS; and USB Micro-B connection to PC for GUI communication via MAX32625PICO bridge.

Can the MAX25460EVKIT# be used in standalone mode without the GUI or PC?

Yes - the MAX25460EVKIT# supports stand-alone operation by reconfiguring resistors per Table 1 (e.g., R6/R7 for LDO-sourced 3.3V, R2/R3/R4 for CONFIG pins), disabling the Pico board interface. In this mode, charge detection, buck enable, and data mode are controlled solely by hardware pins (DATA_MODE, ENBUCK, HVEN) and external pull-ups/pull-downs.
